Enforce current-only publication state contracts

[efraespada]

This PR removes legacy publication and persisted-state compatibility paths and tightens the remaining contracts. It also makes partial Bugbot coverage explicitly block pull request readiness until maintainer review.

What changed

• Removed legacy recommendation text, watermark handling, and compatibility markers in favor of structured publication state.
• Made persisted recommendation and deployment snapshots strict, including exact fields and required failure evidence for blocked deployments.
• Updated lifecycle handling so partial Bugbot coverage removes state:ready and applies state:blocked with state:awaiting-maintainer.
• Updated focused tests, documentation, specifications, and generated bundles to reflect the simplified contracts and partial-review behavior.
