Add ASP.NET Core PR attention canvas

[PureWeen]

Summary

• adds the project-scoped ASP.NET Core Team App canvas backed by the deterministic PR Attention skill in Add pull request attention queue skill #69040
• presents separate Review now and Needs rescue lanes, a compact Ready to merge strip, expandable secondary classifications, and a dedicated Verify discussion lane
• renders visible items by the engine-provided digestRank rather than deriving a second order in the UI
• supports explicit digest-only author exclusion while preserving the full matched census
• validates additive JSON fields while remaining compatible with earlier 1.0.0 producers
• provides only read-only Open PR, Review, and Investigate rescue actions through opaque server-owned item IDs, stale-safe snapshots, and same-origin loopback protection

Discussion-evidence boundary

The canvas does not reinterpret the deterministic classification or next actor. It displays bounded top-level discussion evidence and current thread state supplied by the skill when a leading raw ReviewNow candidate must be checked before ordinary review.

A Verify discussion card exposes only Open PR. Review actions are denied for verification-needed and not-assessed entries. It is used when the skill finds an explicit author close/continue disposition, actionable or unknown non-author discussion, incomplete data, or a current unresolved inline thread without collected thread-comment text. Resolved and outdated threads remain visible factual context but do not infer ownership. Comment excerpts render through DOM textContent and never reach action prompts.

Thus #67146 is held for its author disposition and #68037 for later non-author discussion, while clear candidates can remain in ordinary Review now. This is not an LLM judgment, an automatic bucket rewrite, or a new mutation surface.

Validation

• pwsh .github/skills/pr-attention-queue/tests/Test-PRAttentionQueue.ps1 passes strengthened fixture coverage for author disposition without formal review, polite actionable owner feedback, initial owner objections, incomplete data, current unresolved threads, and resolved/outdated thread controls.
• node --test .github/extensions/aspnetcore-team-app/*.test.mjs passes all 24 tests.
• Earlier complete live and runtime verification confirmed complete enumeration, caller exclusion, distinct Verify discussion behavior for Fix null reference issue caused by validation exception when circuit is disposed #67146/Avoid defensive copies of RenderTreeFrame in RenderBatchWriter.Write #68037, clear ordinary candidates, and no Review action for verification cards.

Stack

This PR is stacked on #69040. Its temporary base branch mirrors the current #69040 head at 3e1700c7d9, so it remains a 13-file canvas-only diff. Review this after #69040 and retarget it to main after the base PR lands.

The source intentionally assesses only leading candidates and caps top-level comments and thread state at 50 per candidate. It does not perform full pagination, retrieve inline-thread comment text, or invoke a semantic model. Current unresolved inline feedback is routed to human verification instead of being called clear.
