PR Review (parallel feature + security)

Run a unified review of the change identified by $ARGUMENTS (a PR number, a branch, or - if empty - the current working-tree diff).

Steps

1. Resolve the diff. If a PR number is given, fetch it via the github MCP (or gh pr diff <n>). If a branch, git diff main...<branch>. Otherwise use git diff of the working tree. Capture the file list and the diff.
2. Fan out, in parallel (single message, two Agent calls):
   • feature-reviewer - correctness, domain accuracy, conventions, tests.
   • security-auditor - threat model of any auth/secret/integration/payload surface in the diff. Pass each agent the diff scope and changed-file list.
3. Wait for both, then synthesise one comment.

Unified output

## Aegis PR Review - <PR/branch>
**Merge verdict: APPROVE | REQUEST_CHANGES | BLOCK (security)**

### Feature review (feature-reviewer)
<verdict + blocking issues>

### Security review (security-auditor)
<verdict + findings; CRITICAL ⇒ BLOCK>

### Combined blocking items
1. [file:line] …

### Non-blocking suggestions
- …

Rules: any CRITICAL security finding ⇒ overall BLOCK regardless of the feature verdict. Any feature blocking issue ⇒ at least REQUEST_CHANGES. If --comment is requested and a PR number is known, post the synthesis as a PR comment via the github MCP.
