Add semantic versioning for releases

Implements semantic versioning for Docker images and GitHub Action
references, enabling version pinning for stability and rollback.

• Release workflow produces vX.Y.Z, vX.Y, and vX tags for images
  with semver validation and pre-release support
• Semi-automated release script with dry-run mode
• All internal action references pinned from @main to @v0
• Versioning docs added to README, action/README, reusable workflows
  guide, and new RELEASING.md

Closes #389

Test plan:

• Trigger release-images.yml via workflow_dispatch with a test tag to
  verify image tagging logic
• Run .github/scripts/create-release.sh v0.0.0-test --dry-run to
  validate the release script
• Grep workflows for remaining @main references (should be none)
• After merge, create v0.1.0 release and verify images in GHCR

Resolved merge conflicts via rebase onto main.

Conflicts resolved:

1. .github/workflows/sdlc-work-loop.yml (line 847)

   • Resolution: Updated action reference to @v0 (the PR's purpose), removed redundant if condition that checked circuit_breaker since the job-level condition already handles this.

2. docs/guides/reusable-workflows.md (Common Parameters table)

   • Resolution: Kept bot_username default as egg (from main branch — correct project default), updated action_ref default to @v0 (the PR's purpose).

All changes verified locally (ruff check passed, YAML valid).

@james-in-a-box pull main into this branch

[james-in-a-box]

The branch is already up to date with main.

Verified that commit 44f2cce (the latest on main: "docs: Remove hardcoded bot username [doc-updater]") is already included in this PR branch. No merge needed.

@james-in-a-box checks are failing on this pr due to the labels missing. Let's create a follow up issue for updating versions for GitHub actions and do that after this is merged so we can get checks passing on this branch.

[james-in-a-box]

Created follow-up issue #475 for updating action references to @v0 after the first release.

The CI failures were caused by a chicken-and-egg problem: the workflows reference jwbron/egg/action@v0, but the v0 tag doesn't exist until a release is made. I've reverted all action references back to @main so CI can pass.

Changes made:

• Reverted @v0 → @main in 9 workflow files (18 occurrences total)
• Created issue Update action references to @v0 after first release #475 to track the follow-up task

Files modified:

• .github/workflows/on-mention.yml
• .github/workflows/on-push-doc-updater.yml
• .github/workflows/on-review-feedback.yml
• .github/workflows/reusable-autofix.yml
• .github/workflows/reusable-conflict-resolve.yml
• .github/workflows/reusable-review.yml
• .github/workflows/sdlc-pipeline.yml
• .github/workflows/sdlc-work-loop.yml
• .github/workflows/self-improvement.yml

The documentation still references @v0 as the recommended approach for users (since the docs describe how to use versioned releases). Once this PR is merged and v0.1.0 is released, issue #475 can be completed to update the internal references.

Agent-Mode Design Review: No concerns.

This PR implements semantic versioning infrastructure for Docker images and GitHub Action references. All changes are standard CI/CD automation:

• Release workflow (release-images.yml): Generates version tags via shell logic — no agent interaction
• Release script (create-release.sh): Human-run tooling for creating releases
• Action reference updates: Mechanical @main → @v0 replacements across workflows
• Documentation: Explains versioning policy for human consumers

None of these changes involve agent prompts, agent output handling, or agent workflow design. The PR is purely about versioning infrastructure for the project itself.

Review Summary

This PR implements semantic versioning infrastructure for Docker images and GitHub Action references. The implementation is generally sound, but I found several issues that should be addressed.

---

Issues Requiring Changes

1. Workflow Logic Bug: Push to Main Now Produces Incorrect Tags

File: .github/workflows/release-images.yml (lines 110-113)

Current logic:

elif [[ "$TAG" != "latest" ]]; then
  # Non-release push to main: add latest tag
  TAGS="${TAGS},${IMAGE}:latest"
fi

Problem: When github.event_name == "push" (push to main), the code sets TAG="latest" on line 63. Then this elif condition is false (since TAG == "latest"), so no additional tags are added. The final TAGS will be just ${IMAGE}:latest.

This matches the original behavior, but the comment is misleading. More importantly, the logic is fragile—if someone changes line 63 to set a different default tag (e.g., main), this condition would suddenly add :latest as a second tag, which may not be intended.

Suggestion: Simplify by making the push-to-main case explicit:

if [[ "$IS_RELEASE" == "true" ]]; then
  # release logic...
else
  # Non-release: just use the tag (already set to "latest" for push events)
  # No additional tags needed
  :
fi

Or document the current behavior more clearly with a comment explaining that push-to-main sets TAG="latest" so this elif is effectively a no-op.

---

2. Pre-release Tags Still Update Floating Tags (vX, vX.Y)

File: .github/workflows/release-images.yml (lines 102-109)

Problem: For pre-releases like v1.0.0-alpha, the code adds floating tags v1.0 and v1:

if [[ "$IS_RELEASE" == "true" ]]; then
  TAGS="${TAGS},${IMAGE}:${MINOR_TAG},${IMAGE}:${MAJOR_TAG}"
  # Only skips :latest for pre-releases

This means v1.0.0-alpha will update the v1 and v1.0 floating tags, which is typically not the desired behavior. Users pinned to @v1 expect stable releases only.

The create-release.sh script has the same issue (lines 179-183)—it always updates floating tags, even for pre-releases.

Suggestion: Skip floating tag updates for pre-releases:

if [[ "$IS_RELEASE" == "true" ]]; then
  if [[ "$IS_PRERELEASE" == "false" ]]; then
    TAGS="${TAGS},${IMAGE}:${MINOR_TAG},${IMAGE}:${MAJOR_TAG}"
    TAGS="${TAGS},${IMAGE}:latest"
  fi
  # Pre-releases only get the exact version tag (e.g., v1.0.0-alpha)
fi

And update create-release.sh similarly:

if [[ "$IS_PRERELEASE" == "false" ]]; then
  run_cmd git tag -f "$MINOR_TAG" ...
  run_cmd git tag -f "$MAJOR_TAG" ...
fi

---

3. Create-Release Script: PATCH Variable Declared but Never Used

File: .github/scripts/create-release.sh (line 120)

PATCH="${BASH_REMATCH[3]}"

This variable is extracted but never used. Either remove it or use it (perhaps in the release notes template).

---

4. Documentation Inconsistency with Implementation

Files: README.md, action/README.md, docs/guides/reusable-workflows.md

The documentation shows examples using @v0, but:

1. The @v0 tag doesn't exist yet (as noted in commit message and issue #475)
2. The actual workflow files reference @main

While issue #475 is meant to address this, the current state is confusing. The documentation promises something that won't work until after the first release.

Suggestion: Either:

• Add a note in the docs: "Note: Use @main until the first release (v0.1.0) is published, which will create the @v0 tag."
• Or wait to merge the documentation changes until after the first release

---

5. Create-Release Script: Missing Sanity Check for Branch

File: .github/scripts/create-release.sh

The script checks for uncommitted changes but doesn't verify it's running from an appropriate branch (e.g., main). Running create-release.sh v1.0.0 from a feature branch would create a release pointing to that branch's HEAD.

Suggestion: Add a warning or check:

CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)
if [[ "$CURRENT_BRANCH" != "main" ]]; then
  log_warn "Creating release from branch '$CURRENT_BRANCH' (not main)"
  read -p "Continue? [y/N] " -n 1 -r
  echo
  if [[ ! $REPLY =~ ^[Yy]$ ]]; then
    exit 1
  fi
fi

---

6. Workflow: BASH_REMATCH Used After Separate Regex Check

File: .github/workflows/release-images.yml (lines 59, 68, 73-75)

The code first checks $TAG =~ ^v[0-9]+\.[0-9]+\.[0-9]+ (line 59), but the capture groups are used from a different regex on line 68. This works because the second regex is run when IS_RELEASE == "true", but it's fragile—if someone modifies line 59's regex to also capture groups, they might expect those to be used.

The current code is correct, but consider consolidating to make the flow clearer.

---

Minor Issues / Suggestions

7. RELEASING.md Rollback Example Contains a Subtle Issue

File: RELEASING.md (lines 104-108)

# Delete the bad tags
git push --delete origin v0.2.0 v0.2 v0
git tag -d v0.2.0 v0.2 v0

# Point floating tags to the last good release
git tag -f v0.2 v0.1.5

If you're releasing v0.2.0 and it's bad, v0.1.5 doesn't exist—you'd want v0.1.x (whatever the last v0.1 release was). The example is illustrative but may confuse readers.

8. Script Output May Contain Untrusted Data

File: .github/scripts/create-release.sh (line 206 onwards)

The heredoc for release notes includes $PREV_TAG which comes from git describe. If tag names contained special characters, they could break the heredoc or the markdown. This is low risk since tag names are controlled, but worth noting.

---

What Looks Good

• The semver validation regex is correct and handles pre-release suffixes
• The dry-run mode in create-release.sh is well implemented
• The workflow structure follows existing patterns
• Documentation is comprehensive
• The chicken-and-egg problem (needing v0 to exist before referencing it) is properly handled via issue #475

---

Recommendation

Request changes due to issues #1-2 (logic bugs affecting release behavior). The floating tag update for pre-releases (#2) is particularly important to fix before this ships—it would cause pre-release versions to override the stable floating tags.

This PR implements semantic versioning infrastructure for Docker images and GitHub Action references. The implementation is partially complete - core infrastructure (Phases 1, 2, 4) is implemented correctly, but Phase 3 (action reference updates to @v0) was intentionally reverted due to a chicken-and-egg problem with the @v0 tag not existing yet.

Verification Details

Phase 1 (release-images.yml):

• .github/workflows/release-images.yml:102-104: Correctly generates vX.Y.Z,vX.Y,vX tags
• .github/workflows/release-images.yml:67-71: Validates semver with proper error annotation
• .github/workflows/release-images.yml:80-83,106-109: Correctly skips latest for prereleases

Phase 2 (create-release.sh):

• .github/scripts/create-release.sh:100-106: Validates semver format
• .github/scripts/create-release.sh:165-178: Creates tags and pushes to origin
• .github/scripts/create-release.sh:61-67: Implements run_cmd() for dry-run mode
• .github/scripts/create-release.sh:187-259: Generates markdown release notes template

Phase 4 (Documentation):

• README.md:266-300: Versioning section with policy and examples
• docs/guides/reusable-workflows.md:9-24: Version Pinning section added
• action/README.md:26-45: Quick Start uses @v0, Version Pinning section added
• RELEASING.md: Complete release guide with checklist

Contract Compliance

The PR correctly addresses the chicken-and-egg problem by:

1. Creating follow-up issue #475 to track the deferred @v0 reference updates
2. Providing clear commit message explaining the reversion reason
3. Keeping documentation examples at @v0 (they serve as future-state documentation)

This is a reasonable approach since workflows cannot reference a tag that doesn't exist yet.

Recommendation

Approve - The core infrastructure for semantic versioning is correctly implemented. Phase 3 tasks are appropriately deferred to a follow-up issue (#475) with clear rationale. The PR provides all necessary tooling to create the first release, after which #475 can be completed.
