hermes - 💡(How to fix) Fix Add PR review digest mode grouped by reviewer value

Motivation

Cursor's pr-review-canvas and docs-canvas plugins contain a useful presentation pattern even without Cursor Canvas runtime: reorganize code review/docs around reader value instead of file-tree order.

Hermes coding operations currently inspect PRs and update dashboards, but review summaries can become file-by-file or status-heavy. A Hermes-native digest mode would make PR review requests faster for Emmanuel by leading with core logic, risk, verification evidence, and only then mechanical changes.

Proposed Hermes adaptation

Add a review digest skill/script mode for GitHub PRs that produces markdown (and optional HTML later) with:

1. Core logic and behavior changes first.
2. Wiring/integration changes condensed.
3. Boilerplate/mechanical/generated diffs summarized by file/stats.
4. Pseudocode for dense changed logic.
5. Concrete before/after traces for surprising behavior changes.
6. Risk callouts (Breaking, Race, Perf, Auth/Data, Migration) only when genuinely useful.
7. Verification block listing exact local/CI gates run and their outcomes.

Do not depend on Cursor Canvas. This should be compatible with gh pr diff, local git diff, and existing Hermes GitHub review skills.

Acceptance criteria

• A Hermes skill or script can take a PR URL/number and emit a reviewer-oriented markdown digest.
• Digest groups by reviewer value, not path order.
• Output includes verification evidence and explicit unanswered questions/blockers.
• Coding ops dashboard can link/store the digest for PRs requiring Emmanuel review.
