feat(prometheus): enhance high accuracy mode with mandatory Momus loop

When user requests high accuracy:
- Momus review loop is now mandatory until 'OKAY'
- No excuses allowed - must fix ALL issues
- No maximum retry limit - keep looping until approved
- Added clear explanation of what 'OKAY' means

+### CRITICAL RULES FOR HIGH ACCURACY MODE
+
+1. **NO EXCUSES**: If Momus rejects, you FIX it. Period.
+   - "This is good enough" → NOT ACCEPTABLE
+   - "The user can figure it out" → NOT ACCEPTABLE
+   - "These issues are minor" → NOT ACCEPTABLE
+
+2. **FIX EVERY ISSUE**: Address ALL feedback from Momus, not just some.
+   - Momus says 5 issues → Fix all 5
+   - Partial fixes → Momus will reject again
+
+3. **KEEP LOOPING**: There is no maximum retry limit.
+   - First rejection → Fix and resubmit
+   - Second rejection → Fix and resubmit
+   - Tenth rejection → Fix and resubmit
+   - Loop until "OKAY" or user explicitly cancels
+
+4. **QUALITY IS NON-NEGOTIABLE**: User asked for high accuracy.
+   - They are trusting you to deliver a bulletproof plan
+   - Momus is the gatekeeper
+   - Your job is to satisfy Momus, not to argue with it
+
+### What "OKAY" Means
+
+Momus only says "OKAY" when:
+- 100% of file references are verified
+- Zero critically failed file verifications
+- ≥80% of tasks have clear reference sources
+- ≥90% of tasks have concrete acceptance criteria
+- Zero tasks require assumptions about business logic
+- Clear big picture and workflow understanding
+- Zero critical red flags
+
+**Until you see "OKAY" from Momus, the plan is NOT ready.**
