fix: restore /last30days slash command on Claude Code v2.1.105+ (#261)

Two regressions were silently breaking /last30days for every user:

1. plugin.json declared "skills": ["./"], which newer Claude Code
   rejects with "Path escapes plugin directory: ./ (skills)". The
   skill loader refused to register the command, so /last30days
   returned "Unknown command" even though /plugin list showed the
   plugin as installed. Fix: "skills": ["skills"] so the loader
   scans the real subdirectory.

2. marketplace.json pinned "version": "3.0.0" while plugin.json
   advertised "3.0.1". The /plugin resolver used the marketplace
   version and could install a phantom user-scope copy at a stale
   SHA alongside the correct project-scope install, creating
   duplicate skill-name collisions. Both manifests now agree on
   3.0.2.

Prior attempt: commit 93fbed2 fixed (1) before but got reverted.
This lands both fixes together in a tagged release so users can
/plugin update to recover.

Recovery for affected users is in CHANGELOG.md under 3.0.2.

+## [3.0.2] - 2026-04-15
+
+### Fixed
+
+- **`/last30days` slash command now registers on Claude Code v2.1.105+.** `.claude-plugin/plugin.json` declared `"skills": ["./"]`, which newer Claude Code rejects with `Path escapes plugin directory: ./ (skills)`. The skill silently failed to register, so `/last30days <query>` returned "Unknown command" even though `/plugin list` showed the plugin as installed. Fix: `"skills": ["skills"]` so the loader scans the real skill subdirectory.
+- **Version drift between manifests.** `.claude-plugin/marketplace.json` was pinned to `3.0.0` while `.claude-plugin/plugin.json` advertised `3.0.1`. The `/plugin` resolver used the marketplace version and could install stale cached metadata alongside the correct build. Both manifests now agree on `3.0.2`.
+
+### Recovery
+
+If `/last30days` stopped working for you, run `/plugin update last30days` then `/reload-plugins`. If `/doctor` still reports errors, uninstall and reinstall the plugin from the marketplace.
