chore: release v0.19.0

[avifenesh]

Summary

Release v0.19.0 - MINOR bump for the new Claude Code output-style validator (CC-OS-001..005), plus 12 catch-up fixes from this week's tool-release watcher run.

Highlights since v0.18.0

New validator (the MINOR bump):

• CC-OS-001..005 - validates .claude/output-styles/*.md (output-style frontmatter spec added in Claude Code v2.1.94). Total rules: 399 -> 404.

Catch-up fixes for upstream tool releases (no regressions, all caught false-positives):

• claude-code v2.1.117 (Tool release: Claude Code v2.1.117 (was v2.1.90) #745), v2.1.118 (fix(claude-code): catch up to v2.1.118 (mcp_tool hook type) #767 mcp_tool hook type)
• codex CLI rust-v0.122.0 (fix(codex): catch up to rust-v0.122.0 (8 new top-level config keys) #758, 8 new top-level keys), rust-v0.123.0 (fix(codex): catch up to rust-v0.123.0 (experimental_thread_store_endpoint) #772 experimental_thread_store_endpoint)
• copilot v0.43.0 (fix(copilot): catch up to v0.43.0 (description frontmatter field) #761 description frontmatter)
• opencode v1.14.20 (fix(opencode): catch up to v1.14.20 (tui.mouse config key) #759 tui.mouse), v1.14.21 (docs(opencode): refresh dates for v1.14.21 (no code changes) #769 docs)
• Pure doc refreshes verified against upstream: cline v3.80.0, cursor 3.1.17, kiro 2.0.1, roo-code v3.52.1, amp, gemini-cli v0.38.2, windsurf Wave 14

Infra:

• Daily tool-release watcher (.github/workflows/tool-release-watch.yml) - the source of all 12 catch-up issues above
• Clippy gate now covers --all-targets --all-features (catches test/bench warnings)
• Playground state shareable via ?file=, ?tool=, ?code= URL params
• [files].exclude now also filters project-level rules (was silently skipping them) ([BUG] .files.exclude not working as expected #722)
• Pre-commit hook respects pass_filenames again ([BUG] The pre-commit hook config defaults to checking every file #723)
• Docs site: /docs/ serves released version, dev moved to /docs/next/
• Release automation: version-docs job now bumps lastVersion so /docs/ flips correctly

Full notes in CHANGELOG.md [0.19.0] section.

Code Review

This pull request bumps the project version to 0.19.0 across all supported platforms and configuration files, including Cargo, VS Code, JetBrains, Zed, and NPM. The changelog has been updated to reflect the addition of new output-style validators, bringing the total rule count to 404. However, the VS Code extension description still references 399 rules and should be updated for consistency.

Addressed reviewer feedback in 98a6c1d:

Both reviewers flagged stale rule count in editors/vscode/package.json description.
Copilot also caught that CHANGELOG said "399 -> 404" while rules.json reports total_rules: 405.

Root cause: the new CC-OS validator added 6 rules (CC-OS-001..006) not 5. CC-OS-006 ("Invalid Output Style Frontmatter Syntax", HIGH) was missing from my draft entry. I also missed the broader doc-sync pass — the same drift PR #721 fixed ("385 -> 399") had recurred.

Fix:

• CHANGELOG: corrected to CC-OS-001..006 and 399 -> 405
• VS Code description: dropped the hard-coded count entirely (per Copilot's suggestion), since this string drifts on every release and the actual count is one click away in the README
• 20 user-facing files bumped 399 -> 405 to match rules.json (CLAUDE.md, AGENTS.md, README.md, SPEC.md, all editor READMEs, knowledge-base/INDEX.md, npm/README.md, plugin manifests, website docs)

Self-lint clean (cargo run -p agnix-cli -- .); no rust changes so test suite unaffected.
