• Follows Studio Code: Bring the remote-site runbook with a WordPress.com active site instead of a rule to load it #5231, which brings the remote-site runbook when a WordPress.com site is active.

How AI was used in this PR

Claude (via the Pi coding agent in a Roadie session) wrote the change and the tests, and ran the eval below on trunk and on this branch. I reviewed the diff and the transcripts.

Proposed Changes

site_list listed only local sites. When the user names one of their WordPress.com sites and no WordPress.com site is active, the agent looked there, found nothing, and concluded the site doesn't exist. Nothing pointed it to WordPress.com, except a line in the remote-site runbook, which is only loaded once the agent already knows the site is remote.

• site_list now returns { local, wordpressCom }. wordpressCom holds the sites the stored login reaches, with the ID wpcom_request takes as siteId. They come from the same getWpComSites() the /site picker uses: about 14 KB for 160 sites, versus 2.4 MB for GET !/me/sites with plan.
• Signed out, it says signedIn: false. If the lookup fails, it reports the error and still lists the local sites.
• Its annotation is now REMOTE_READ, like site_connected_remote_sites. That tool is still read-only, so hosts run it without asking.
• The remote-site runbook points to site_list for other sites instead of site_connected_remote_sites or GET !/me/sites.

Testing Instructions

• npx vitest run apps/cli/ai/tests/tools.test.ts: it lists local and WordPress.com sites together, reports a signed-out user, and keeps the local sites when WordPress.com can't be reached.
• Eval: two prompts naming a WordPress.com site (a Business plan Atomic site) while no WordPress.com site is active, 4 runs each per arm, with trunk and this branch as two providers in one promptfoo config.

Prompt	Trunk	This branch
"Which theme is my Franklin Works site using?" (no active site)	0/4: asked which site was meant; one run grepped ~/Studio with Bash	4/4: site_list, then one wpcom_request
"Add a draft post titled 'Site list eval' to my Franklin Works site." (a local site active)	0/4: offered the local site or a new one; one run used Bash	4/4: a draft on the right site, without touching the local site

No run on either arm called GET !/me/sites. Median tokens went from 37k to 52k (theme) and from 32k to 53k (draft), because the branch finishes the task where trunk stopped to ask. The drafts were trashed afterwards.
