Tam Nhu Tran 7396179c72 feat(ci): bound ai review runtime for large PRs 
- add trusted scope generation for bounded ai-review runs
- restrict large PR reviews to a prepared read-only workspace
- render explicit mode, scope, and budget metadata in review comments

# AI Code Review Workflow
# Uses anthropics/claude-code-action with GLM routing via GitHub App tokens
# Same-repo PRs stay on the self-hosted cliproxy runner; external PRs use ubuntu-latest
#
# Triggers:
# - Automatically when PR is opened, receives new commits, or is reopened
# - Manually via /review comment on PR
# - Manually via workflow_dispatch
#
# Note: Concurrency group cancels in-progress reviews when new commits arrive.
# This prevents wasting resources on outdated code reviews.

# Smart concurrency: Prevents self-cancellation when non-command comments arrive
#
# Problem: When a bot or maintainer posts a normal PR note, GitHub fires an
# issue_comment event. A loose substring match on "/review" can accidentally
# treat text like "CI/review" as a manual command, which joins the PR
# concurrency group and cancels the in-progress review.
#
# Solution: Non-actionable triggers (bot comments, comments without /review) get a
# unique per-run group, while legitimate triggers share the PR-based group for proper
# cancellation of outdated reviews.

## Runtime Rules
- This is a READ-ONLY review. Do not edit files.
- Read `.ccs-ai-review-scope.md` first. It is the authoritative bounded review input for this run.
- Start with the generated scope file, then read only the selected PR files and `.ccs-ai-review-base/<path>` snapshots available in the bounded workspace.
- Respect the selected review mode budget and scope. Do not try to exhaustively map the repository on auto runs.
- If the mode is `triage`, prioritize hotspots and be explicit that the review was bounded rather than exhaustive.
- Do not reconstruct the full PR diff for `fast` or `triage` reviews, and do not look for omitted files outside the bounded workspace.
- Return only structured output that matches the provided JSON schema.
- Do NOT write files.
- Do NOT post GitHub comments yourself.
- If no confirmed issues remain, return an empty findings array instead of inventing low-value feedback.
