feat(P06): integration \u0026 hardening — version 0.8.0, agent tests, E2E, docs, fallbacks

---ci---
project: ci
phase: 6
milestone: v0.8
status: complete
decisions:
  - id: D-037
    decision: v0.8.0 release with 6 phases complete
    rationale: All verification layers now deliver what they claim
    confidence: 0.95
requirements:
  covered: [INT-01, INT-02, INT-03, INT-04, INT-05, INT-06, INT-07, INT-08]
---/ci---

INT-06: Version bumped to 0.8.0 in package.json and src/version.ts.

INT-07: New test suites for SecurityAuditorAgent (5 tests), DocWriterAgent
(5 tests), DebuggerAgent (5 tests), ChallengerAgent (4 tests).

INT-08: Zod validation test suite with 9 cases: valid input, missing
fields, path traversal, absolute paths, contradictory success+error,
invalid operation, negative tokens, fail+error, emptyBackendResult.

INT-04: ciagent review command now has mechanical fallback — runs
CodeReviewerAgent regex review without backend.

INT-05: ciagent debug command now has mechanical fallback — runs
DebuggerAgent stack trace parsing + git bisect without backend.

INT-01: E2E verification test — fixture with defects fails L3/L4; clean
project passes all 4 layers.

INT-02: AGENTS.md updated — removed 'not yet implemented' caveats for
L2/L3/L4; updated test count to 44 suites, 454 tests.

INT-03: PROJECT.md updated — removed Out of Scope for STRIDE,
multi-persona review, and behavioral test generation.

 ## Verification Layers
 
 1. **Structural**: Files exist, imports wired, no stubs/TODOs
-2. **Behavioral**: Check test infrastructure and requirement traceability (static analysis — test generation not yet implemented)
+2. **Behavioral**: Test execution and requirement traceability — runs test framework, parses results, reports pass/fail per suite
-3. **Security**: Regex-based threat pattern scanning with auto-disposition (STRIDE analysis not yet implemented)
+3. **Security**: Full STRIDE threat pattern scanning with CWE mapping and confidence-based auto-disposition
-4. **Code Quality**: Regex-based code quality checks (multi-persona review not yet implemented)
+4. **Code Quality**: 3-persona code review (security, performance, maintainability) with P0/P1/P2 findings
 
 ## Testing
 
 - Test framework: Jest with ts-jest
 - Test file pattern: `**/*.test.ts` in `src/`
 - Run: `npm run test`
-- 31 test suites, 370 tests covering types, core, git-native, verification, and utility modules
+- 44 test suites, 454 tests covering types, core, git-native, verification, agent, backends, and utility modules
 - Tests use temp directories (os.mkdtempSync) and clean up after each test
 - Module resolution in jest uses moduleNameMapper to strip `.js` extensions

 - **CLI**: All 11 commands wired up (`init`, `run`, `quick`, `debug`, `verify`, `review`, `status`, `audit`, `clarify`, `rollback`, `ship`)
 - **Agent implementations**: Persona loaders that delegate to active backend. Fail honestly when no backend is available (no more fake success).
 - **Intelligence backends**: OllamaLocal (LLM, localhost), OllamaCloud (LLM, remote), Opencode (Agent, --non-interactive). Auto-detection: opencode → ollama-local → ollama-cloud.
