fix(v0.7.12): stabilize production recovery and knowledge site layout

[qiansc]

Partial delivery could require candidate links to be approved before review, while an independent article revision could inherit production review authority or clear an unfinished production stage. This change separates review and delivery checks, preserves the interrupted stage through revision/build failures, and prevents premature lifecycle cleanup.

Also refresh retained planning materials after repository recovery, expose task-adjustment schema guidance, fix responsive navigation and Mermaid sizing, and prepare package/workflow/plugin versions and the community lock for 0.7.12.

Validation on the submitted source:

• Package type checks and full build passed; CLI lint has no errors (32 existing warnings).
• Relevant workflow, recovery and site regression suite: 147 passed; expanded independent-revision retry tests: 2 passed.
• Actual Node CLI artifact tests: 2 passed; release preparation passed.
• Browser checks at 390, 768, 1024 and 2560 px found no horizontal overflow; diagrams retain their natural maximum width.

This is a targeted regression verification, not a completed full release gate. No packages have been published by this change.
