<objective>
Check for GSD updates, install if available, and display what changed.

Routes to the update workflow which handles:
- Version detection (local vs global installation)
- npm version checking
- Changelog fetching and display
- User confirmation with clean install warning
- Update execution and cache clearing
- Restart reminder
</objective>

<execution_context>
@~/.claude/get-shit-done/workflows/update.md
</execution_context>

<flags>
- **--sync**: Sync managed GSD skills across runtime roots so multi-runtime users stay aligned after an update. Runs the sync-skills workflow (--from, --to, --dry-run, --apply flags supported).
- **--reapply**: Reapply local modifications after a GSD update. Uses three-way comparison (pristine baseline, user-modified backup, newly installed version) to merge user customizations back. Runs the reapply-patches workflow.
- **(no flag)**: Standard update — check for new version, show changelog, install.
</flags>

<process>
Parse the first token of $ARGUMENTS:
- If it is `--sync`: strip the flag, execute the sync-skills workflow (passing remaining args for --from/--to/--dry-run/--apply).
- If it is `--reapply`: strip the flag, execute the reapply-patches workflow.
- Otherwise: **Follow the update workflow** from `@~/.claude/get-shit-done/workflows/update.md`.

The update workflow handles all logic including:
1. Installed version detection (local/global)
2. Latest version checking via npm
3. Version comparison
4. Changelog fetching and extraction
5. Clean install warning display
6. User confirmation
7. Update execution
8. Cache clearing
