Set up unattended extension releases so release-worthy squash commits on
main are published only after the complete CI and host compatibility gate
passes. Merging this PR intentionally enables the first Semantic Release run,
which will start at v1.0.0 from the existing Conventional Commit history.

What changed

  • add a tested Semantic Release policy where features are minor releases,
    fixes/performance/reverts/docs are patches, and breaking changes are majors
  • keep the tracked manifest at 0.0.0 while injecting the calculated version
    into one deterministic, checksummed VSIX
  • generate current-release changelog content transiently for the VSIX while
    keeping GitHub Releases as the cumulative history
  • gate release creation on validation plus desktop-floor, desktop-stable, and
    web-stable host jobs, then independently publish the same artifact to Visual
    Studio Marketplace, Open VSX, and the matching GitHub Release
  • validate PR titles as metadata-only Conventional Commits, including lowercase
    subjects and the explicit release vocabulary
  • document release behavior, recovery, GitHub App permissions, squash settings,
    and required checks

The release tooling is fully pinned. The Conventional Commits preset stays at
9.3.1 because the current release-notes generator silently drops entries with
the newer writer contract; an executable notes test protects that boundary.

Testing

  • mise run verify
  • explicit 1.2.3 VSIX packaging and embedded-version inspection
  • mise run release:check
  • mise run ci:workflows
  • pnpm audit --audit-level high

Repository settings still need to be applied after the new check names have run
once: squash-only merging with PR-title squash commits, followed by the required
checks documented in docs/releases.md.

Changes

Release automation

Layer / File(s) Summary
Package contracts and preparation
.vscodeignore, AGENTS.md, eslint.config.mts, mise.toml, package.json, scripts/lib/*, scripts/package.mts, scripts/prepare-release.mts, test/manifest.test.mts, test/package-content.test.mts, tsconfig.tooling.json
Packaging creates versioned VSIX files, validates archive contents, generates SHA-256 checksums, and supports release-specific tasks and scripts.
Semantic Release configuration and outputs
CHANGELOG.md, release.config.mjs, scripts/lib/release-config.mts, scripts/lib/release.mts, scripts/release.mts, test/release.test.mts
Semantic Release maps Conventional Commits to versions and notes, prepares packages, creates GitHub releases, and writes standardized release outputs.
CI release and artifact publication
.github/workflows/ci.yml, docs/testing.md, test/workflows.test.mts
Main-branch CI runs the release after validation, uploads one immutable artifact, verifies its checksum, and publishes it to Visual Studio Marketplace, Open VSX, and GitHub Releases.
Semantic pull-request validation
.github/workflows/semantic-pr.yml, docs/plans/004-semantic-release-automation.md, test/workflows.test.mts
A pull-request workflow validates Conventional Commit titles, reports errors with sticky comments, removes resolved comments, and cancels superseded runs.
Release policy and operational documentation
README.md, docs/architecture.md, docs/plans/004-semantic-release-automation.md, docs/releases.md, docs/testing.md
Documentation defines release versioning, transient changelogs, publication controls, recovery procedures, testing commands, and repository requirements.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 213e1

The PR adds automated release and title-validation workflows, but the current implementation can still block valid merges when review-comment cleanup fails, recreate stale title feedback from superseded runs, and report a stricter lowercase rule than it enforces. These are bounded CI correctness issues that require owner follow-up before the change is fully merge-ready.

In @.github/workflows/semantic-pr.yml:
- Around line 45-46: Update the “Comment on invalid PR title” step condition to
exclude canceled workflow runs by adding !cancelled() while preserving the
existing error_message check.
- Around line 42-43: Update subjectPatternError to state that the subject must
not start with an uppercase character, matching the behavior of subjectPattern.
- Around line 63-68: Add continue-on-error: true to the “Remove PR title lint
comment” step using marocchino/sticky-pull-request-comment, so cleanup API
failures do not fail the “Validate PR title” job while preserving the existing
condition and deletion behavior.

Scope workflow contract assertions to named YAML nodes. Raw-text matches can pass when a duplicate expression appears in the wrong job or block.

  • test/workflows.test.mts#L69-L80: assert the concurrency group and release guard from their actual workflow and release nodes.
