Enhanced Docs Discovery & Member Registry

New Features

• Triggers documentation readiness discovery when the first repository is linked to a project.
• Introduces AI-powered validation of discovered documentation URLs, confirming that search and README candidates document the intended project.
• Allows docs overrides to mark a project as having no documentation, supporting accurate coverage tracking.
• Adds a script to bulk-apply reviewed documentation overrides, enabling large-scale corrections in a single operation.
• Adds an Akrites member registry and affiliation resolver for mapping contributors to member company organizations.

Bug Fixes

• Prevents sub-projects from inheriting documentation pages belonging to a parent project or foundation.
• Stops platform and tool pages from being incorrectly selected as a project's documentation site.
• Retries the documentation liveness probe on timeouts, server errors, and network failures to reduce missed detections.
• Preserves correct README-based documentation picks when the AI validator returns an inconclusive result.
