* ci: enforce dependency lock stability and slim SDK test jobs
- add dependency-stability workflow: go mod tidy diff for all Go modules,
uv lock --check for all Python projects, pnpm frozen-lockfile check
- fix kubernetes go.mod/go.sum not tidy (drop stale pgzip indirect dep)
- merge cli and python SDK quality+test jobs into one per language
- merge kotlin SDK matrix into a single job running both gradle tasks
* ci: remove unused release-generic workflow
It ran once (failed) in 4 months; the release process uses tag pushes
that trigger publish-* workflows directly. Source archive uploads are
dropped; docs updated to mark source archives as legacy (pre-2026-08).
* ci: also validate docs pnpm lockfile in stability check
