ci/woodpecker/pr/pr-review Pipeline was successful
chore(ci): make ci-claude reproducible and keep it on latest (#351)
The ci-claude image installed a fixed, pinned Claude Code version and every
consumer pipeline pinned a stale dated image tag. Two problems:

- The npm install layer changed on every build (install-time mtimes + the
  npm cache), so it never deduped in the Gitea registry — the single largest
  orphan pattern behind #336 (~260 MB orphaned per no-op rebuild).
- A frozen version silently rots: old Claude Code releases eventually stop
  working against the API.

Containerfile: default to @latest (npm auto-selects the musl native binary on
this alpine base) and make the install layer byte-stable — clean the npm cache
and normalize install-time mtimes on the installed tree and the directories the
RUN touches. Two independent --no-cache builds now produce a byte-identical npm
layer, so a rebuild of the same version dedups instead of orphaning a copy.

New ci-claude-refresh.yml owns the image lifecycle: weekly (and on-demand) it
resolves the latest published version, and only when it differs from what the
consumers pin does it build ci-claude:<version> (+:latest) and open a PR
rewiring the 5 consumer pipelines. Version tags make "did it change?" a
race-free string compare and keep the cron from opening no-op PRs. Nothing
auto-merges. build-ci-images.yml no longer builds ci-claude so the two never
fight over tags.

Requires owner setup before it does anything (documented in the pipeline
header): a dedicated ci-claude-bump-bot identity (write:repository only) as the
ci_claude_bump_bot_token secret, and a cron named "ci-claude-refresh".
