Add AI-based Performance Tuning Recommendations as Site Health Tab (requires WP 7.0)

Feature Description

Propose adding actionable AI-based performance tuning recommendations, leveraging system details as input context when AI functionality is available (requires WordPress 7.0 or higher). The feature could be implemented as a new tab within the Site Health screen. This will allow site administrators to receive targeted, automated advice for optimizing site performance based on real system/server/application data.

See https://github.com/adamsilverstein/wp-performance-wizard for reference - this issue proposes something similar to this plugin. Proposing this for the core plugin now because AI has become sophisticated enough to provide useful, actionable recommendations - and soon will likely be making those fine tuning adjustments on the users behalf.

Key points:

• Provide actionable and specific performance improvements, not just generic suggestions.
• Integrate as a dedicated tab in the Site Health UI for discoverability and user experience.
• Detect presence/availability of AI and surface recommendations only when supported (WP 7.0+).

Potential benefits:

• Faster site optimization, especially for less technical users
• Personalized tuning based on actual environment/context
• Easier troubleshooting by tying recommendations to detected pain points and system configuration

Requirements:

• WordPress 7.0+ for AI availability
• At least one AI service available/connected
• Security/privacy considerations for any system context sent to AI services

Start by reviewing the existing Site Health screen and the referenced wp-performance-wizard plugin to understand the proposed tab and recommendation flow. Then investigate WordPress 7.0 AI availability, system-context handling, and privacy requirements; done means the feature scope, availability gating, recommendation behavior, and security boundaries are specified well enough to implement.
