ci: adopt shared @btravstack reusable CI + release workflows

[btravers]

What

Migrate CI and release to the shared reusable workflows in btravstack/config (the proven pattern, already green in unthrown).

CI (.github/workflows/ci.yml)

• Replaced the common jobs (format, lint, typecheck, knip, test, build, security-audit, changeset) with a single call to btravstack/config/.github/workflows/ci-reusable.yml@main.
  • changeset: true — the changeset gate now runs inside the reusable ci job (and is auto-skipped for the changeset-release/main PR).
  • test-command: "pnpm test -- --coverage --reporter=default --reporter=github-actions" — preserves the non-default test command.
  • knip left at its default (true) — the old knip job was plain (pnpm exec knip ...), no extra steps.
  • security-audit left at its default (true).
• Kept the bespoke jobs verbatim: test-integration, bundle-size (needs: build -> needs: ci), package-check, node-floor.

Release (.github/workflows/release.yml)

• Replaced the inline changesets steps with a call to btravstack/config/.github/workflows/release-reusable.yml@main, passing RELEASE_PAT. The old version/publish commands (pnpm run version / pnpm run release) are the reusable's defaults, so no overrides needed.

Note

• Dropped the unit-test coverage-artifact upload (coverage-report) — the reusable ci job runs tests but does not upload coverage. The integration coverage upload stays (it lives in the bespoke test-integration job).
• deploy-docs.yml and .github/actions/setup untouched.

Pull request overview

Migrates this repository’s CI and release pipelines to the shared reusable workflows in btravstack/config, consolidating the common “gate” steps into a single reusable job while keeping repo-specific jobs in-repo.

Changes:

• Replaced the multi-job CI gate (format/lint/typecheck/knip/test/build/audit/changeset) with a single call to btravstack/config/.github/workflows/ci-reusable.yml@main.
• Replaced the inline Changesets-based release workflow with a call to btravstack/config/.github/workflows/release-reusable.yml@main, passing RELEASE_PAT.
• Updated the bundle-size job dependency to wait for the new ci gate job.
