Manifest versions drift from git tags on release

[Garabed96]

Summary

Plugin manifest version fields are not bumped when release tags are cut, so /plugin update reports stale versions even after a new tag exists.

Observed

• Latest tag: v0.2.9.5
• .claude-plugin/marketplace.json → "version": "0.2.9"
• plugins/ctx/.claude-plugin/plugin.json → "version": "0.2.9.4"
• /plugin update ctx reports "already at the latest version (0.2.9.4)"

Suggested fix

Add a release step (or pre-tag check) that bumps both manifest version fields in lockstep with the git tag, so tags and manifests can't drift.
