Teach Studio Code to recommend Automattic plugins for more features

• Related to: Studio Code should suggest Automattic's own products/plugins (Newsletters, Forms, courses, polls, etc.) instead of re-inventing the wheel.

How AI was used in this PR

The skill/instruction copy was drafted with AI. Every factual claim — plugin slugs, block names, custom post types, and Jetpack module behavior — was verified against real local Studio sites (created via the CLI, installed each plugin, enumerated registered blocks/modules/CPTs, then deleted the probe sites). Reviewers should sanity-check the wording and the Jetpack Newsletter caveat.

Proposed Changes

Studio Code already routes feature requests to a plugin-recommendations skill, but it only covered WooCommerce and Jetpack Forms — so for newsletters, courses, and polls the agent had no named Automattic product to reach for and could fall back to hand-building markup.

This broadens that guidance so the agent reuses Automattic's own products first:

• A feature → Automattic-plugin map (WooCommerce, Jetpack Forms, Jetpack Newsletter, Sensei LMS, Crowdsignal, Jetpack Social, Akismet) as a single source of truth.
• Per-product guidance for the previously-missing gaps: Jetpack Newsletter, Sensei LMS (courses/lessons/quizzes), Crowdsignal (polls/surveys/ratings), and Akismet (spam).
• The system prompt's skill-routing triggers now include newsletters, online courses/LMS/quizzes, polls/surveys, and social auto-posting, so these requests actually load the skill.

User impact: when someone asks Studio Code for a newsletter signup, a course, a poll, etc., it recommends and installs the matching Automattic plugin and builds with its editable blocks, rather than generating a bespoke HTML/JS equivalent.

One deliberate honesty note in the skill: Jetpack Newsletter's subscriptions module cannot activate on a purely local site (it depends on WordPress.com to manage subscribers/send email — confirmed it fails even in Jetpack offline mode). The skill still recommends Jetpack Newsletter as the right tool and explicitly tells the agent not to substitute a hand-built form when the module is unavailable locally.

Testing Instructions

• npm run cli:build
• npm test -- apps/cli/ai/tests/ — all AI tests pass (skill routing + "references only bundled skills" covers the new copy).
• npm run typecheck — clean.
• Optional manual check: studio code → ask for a contact form (installs Jetpack Forms), a course site (installs Sensei LMS), or a poll (installs Crowdsignal) and confirm it reaches for the plugin rather than hand-building.

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Superseded by #4023, which moves the same changes onto fix/improve-plugin-recommendations (rebased on current trunk).
