/**
 * Creates the `skaile update` command.
 *
 * Two stages:
 *   1. **Catalog cache refresh** — invalidates the {@link RemoteCatalogSource}
 *      cache at `~/.skaile/cache/catalog/` and re-fetches the asset list. This
 *      is the Phase 2 entry point for users in air-gapped mode
 *      (`catalog.cache_ttl: 0`) or anyone who wants a fresh view of the public
 *      skaile.store catalog before installing.
 *   2. **Asset re-deploy** — `AssetManager.install()`
 *      re-deploys any outdated assets in the current project from updated
 *      repositories. This is the Phase 1 behavior; preserved here.
 *
 * Pass `--no-catalog` to skip stage 1 (asset-only); pass `--catalog-only` to
 * skip stage 2 (catalog-only). The default runs both.
 *
 * Before re-deploy, `update` offers to **sync sources** from upstream (default
 * yes). Re-deploy resolves against the local source cache, which is frozen at
 * the commit captured when each source was first cloned — without a sync,
 * `update` can never see newer GitHub commits and always reports "Nothing to
 * update". Pass `--no-sync` to skip, `-y`/`--yes` to sync without the prompt; a
 * non-interactive shell defaults to syncing.
 *
 * @returns Configured {@link Command} ready for `program.addCommand()`.
