Summary

Adds a project skill that describes the release workflow used for v0.9.4 and v0.9.5, so a release can be prepared and published from one instruction. The skill is documentation for the agent; it changes no library code.

Changes

• .claude/skills/release/SKILL.md: release PR steps (changelog, performance note with a measurement method, version bumps, registration), post-merge steps (tag, GitHub release, portfile SHA512), and the sentomk/vcpkg and microsoft/vcpkg update.
• States the standing rules: single-commit PRs, Conventional Commits, Summary / Changes / Testing PR bodies, no Co-Authored-By trailer.

Testing

• Docs only. The steps were checked against the v0.9.4 release PR and the merged microsoft/vcpkg PRs for patternia.
• Commit message checked with scripts/check_commit_msg.py.

Docs-only change, and the workflow matches the repo — approving.

Checked

• The rules it cites are real: scripts/check_commit_msg.py enforces the Conventional Commits subject (type list, imperative, lowercase, no trailing period), and .github/workflows/validate.yml checks for the bold **Summary** / **Changes** / **Testing** sections.
• The files and options it names exist: PTN_BUILD_TESTS in CMakeLists.txt, the version in project(... VERSION ...), and packaging/vcpkg/portfile.cmake / vcpkg.json. The note about keeping upstream's REPO sentomk/patternia casing makes sense, since the in-repo portfile uses SentoMK/patternia.
• Phase 1 mirrors what the v0.9.5 release PR did (release note, perf note, page registration in three places, version bumps), and keeping the portfile SHA512 out of the release PR is the right call since it needs the tag.

One non-blocking nit (inline): the vcpkg fork step describes the commit order twice in ways that read as contradictory. Details on the line.

Re-reviewed the force-push to 0da25e9. The only change from eb3555a is Phase 1 step 1: the release branch is now release/X.Y.Z (no v) instead of chore/release-vX.Y.Z. That's consistent with the rest of the skill (the tag and patternia-X.Y.Z fork branch carry their own prefixes) and doesn't affect any other step.

The earlier non-blocking nit about the x-add-version / commit order in Phase 2 step 4 still applies, but it isn't a blocker. LGTM.

Benchmark comparison (informational)

Base 0a0650a vs PR ceb0db2, run one after the other on the same GitHub-hosted runner. This does not block merging.

Noise estimate: the 20 control rows below do not run Patternia code, so they should not change between base and PR. As a group they moved by a median of +0.0% (run order and machine drift); that offset is divided out of the Patternia deltas (Adjusted). The controls then scatter by a median of 0.4%. Adjusted differences under 5.0% are treated as noise.

Patternia: 8 benchmarks, 0 slower, 0 faster, 8 within noise.

Raw results and the comparison chart are attached to this workflow run as an artifact. Shared runners are noisy, so use this as a trend, not a measurement.
