feat(atlas): enforce mandatory manual code review and direct boulder state checks

- VERIFICATION_REMINDER: add Step 2 manual code review (non-negotiable)
  - Require Read of EVERY changed file line by line
  - Cross-check subagent claims vs actual code
  - Verify logic correctness, completeness, edge cases, patterns
- Add Step 5: direct boulder state check via Read plan file
  - Count remaining tasks directly, no cached state
- BOULDER_CONTINUATION_PROMPT: add first rule to read plan file immediately
- verification-reminders.ts: restructure steps 5-8 for boulder/todo checks
- Atlas default.ts (Claude): enhance 3.4 QA with A/B/C/D sections
  - A: Automated verification
  - B: Manual code review (non-negotiable)
  - C: Hands-on QA (if applicable)
  - D: Check boulder state directly
- Atlas gpt.ts (GPT-5.2): apply same QA enhancements with GPT-optimized structure
- verification_rules: update both Claude and GPT versions with manual review requirements

Addresses issue where Atlas would skip manual code inspection after delegation,
leading to rubber-stamping of broken or incomplete work.

 1. \`lsp_diagnostics(filePath=".")\` → ZERO errors
 2. \`Bash("bun run build")\` → exit 0
 3. \`Bash("bun test")\` → all pass

+#### B. Manual Code Review (NON-NEGOTIABLE)
+1. \`Read\` EVERY file the subagent touched — no exceptions
+2. For each file, verify line by line:
+
+| Check | What to Look For |
+|-------|------------------|
+| Logic correctness | Does implementation match task requirements? |
+| Completeness | No stubs, TODOs, placeholders, hardcoded values? |
+| Edge cases | Off-by-one, null checks, error paths handled? |
+| Patterns | Follows existing codebase conventions? |
+| Imports | Correct, complete, no unused? |
+
+3. Cross-check: subagent's claims vs actual code — do they match?
+4. If mismatch found → resume session with \`session_id\` and fix
+
+**If you cannot explain what the changed code does, you have not reviewed it.**
+
+#### C. Hands-On QA (if applicable)
+| Deliverable | Method | Tool |
+|-------------|--------|------|
+| Frontend/UI | Browser | \`/playwright\` |
+| TUI/CLI | Interactive | \`interactive_bash\` |
+| API/Backend | Real requests | curl |
+
+#### D. Check Boulder State Directly
+After verification, READ the plan file — every time:
+\`\`\`
+Read(".sisyphus/tasks/{plan-name}.yaml")
+\`\`\`
+Count remaining \`- [ ]\` tasks. This is your ground truth.
+
+Checklist (ALL required):
+- [ ] Automated: diagnostics clean, build passes, tests pass
+- [ ] Manual: Read EVERY changed file, logic matches requirements
+- [ ] Cross-check: subagent claims match actual code
+- [ ] Boulder: Read plan file, confirmed current progress
