chore(ai): remove dead code (agent)

Removed unused exports and functions identified as dead code.
- Removed unused exports from `js/utils/storage.js`, `js/utils/storagePointer.js`, `js/utils/videoTags.js`, `js/ui/moderationCopy.js`.
- Removed unused function `updateTagPillStrip` from `js/ui/components/tagPillList.js` and associated tests.
- Updated `tests/utils/video-tags.test.mjs` to remove test for private function.
- Added `artifacts/depcheck.json` showing dependency analysis.
