fix: remove worktree and plan-mode from loader and README (not bundled)

These extensions were removed from the repo but the loader still
referenced them and the README still listed them. Removed from:
- src/loader.ts extension entry points (11 → 9)
- README bundled extensions table
- app-smoke test assertions
