v3.0.0

New Features

• Added release-blocking PHPCS, PHPStan, line-coverage, and RSVP helper performance gates, with machine-readable coverage artifacts in CI.
• Added a documented composition root and compensating rollback across event post, metadata, taxonomy, and shared EventON taxonomy-option writes.

Improvements

• Extracted RSVP attendee storage access and response formatting into focused repository and formatter classes while preserving the existing procedural callbacks for compatibility.
• Pinned every GitHub Action to an immutable commit and enabled weekly Composer dependency updates through Dependabot.
• Corrected the settings UI and UI documentation so MCP schema routes are consistently described as requiring administrator authentication.
• Kept development-only Composer tooling and dependencies out of packaged release assets.

Bug Fixes

• Prevented failed multi-stage event writes from silently retaining avoidable partial post, metadata, taxonomy, or shared EventON taxonomy-option changes.
• Removed contradictory settings copy that described protected MCP schema routes as public.
