Respect --path in pull-reprint to overwrite or create a site at that location

How AI was used in this PR

Claude Code (Opus 4.8) wrote the --path handling and its tests; I drove the design decisions (when to overwrite vs. create, the PR base), reviewed the diff, and verified each routing mode live. Lint, typecheck, and the pull-reprint unit tests pass.

Proposed Changes

studio pull-reprint ignored --path and always created a new site under ~/Studio/<name-from-url>, so there was no way to pull into a chosen location or refresh an existing local site.

The resolved path — an explicit --path, or the current directory by default — now decides the target:

Situation	Result
A Studio site is registered at the path	Overwrite it, like studio pull — the site keeps its identity (same id, port, URL, settings) rather than becoming a new entry
Explicit --path, no site there	Create the new site at that path, named after the folder
No --path, current dir isn't a site	Unchanged — create under ~/Studio/<name-from-url>

Overwriting replaces a site's files and database, so it asks for confirmation first (honoring --yes and non-interactive callers) and leaves everything untouched if you decline.

Testing Instructions

Needs a built CLI and STUDIO_ENABLE_PULL_REPRINT=true. The path routing below is observable from the early Site directory: / prompt output; a full pull additionally needs a packaged build that bundles reprint.phar.

1. Create at an explicit path — … pull-reprint --url <site> --path ~/Studio/my-new-site --verbose → Site directory: ~/Studio/my-new-site, site named my-new-site (not the URL default).
2. Overwrite by path — point --path at a registered site's folder → prompt reads "This will overwrite the local site …"; declining leaves the site and cli.json untouched.
3. Overwrite the current site — run with no --path from inside a registered site's directory → same overwrite prompt.
4. Default create — run with no --path from a non-site directory → new site under ~/Studio/<name-from-url>.
5. Unit tests — npm test -- apps/cli/commands/tests/pull-reprint.test.ts
