feat: upgrade story-full-pipeline to v4.0 with 6 major enhancements

Major changes to story-full-pipeline workflow:

1. **Inspector Agent Enhancement**
   - Changed from general-purpose to testing-suite:test-engineer subagent
   - Added BMAD Inspector persona (Vera) with evidence-based verification
   - Requires file:line citations for every task verification

2. **Test Quality Agent Enhancement**
   - Changed from general-purpose to testing-suite:test-engineer
   - Specialized for test coverage and quality analysis

3. **New Inspector Agent Definition** (src/bmm/agents/inspector.agent.yaml)
   - Persona: Vera the Verification Inspector
   - Principles: Evidence-first, file:line citations, quality gates binary
   - Critical actions: Run quality gates, verify coverage, parse actual output

4. **Quality Gates** (v4.0)
   - 80% coverage threshold required
   - Task verification requires file:line evidence
   - Critical/High issues must be fixed

5. **Playbook Learning** (v4.0)
   - Reflection agent extracts patterns for future agents
   - Auto-discovery from git history, docs, existing code

6. **Resume Builder**
   - Fixer agent resumes Builder context instead of fresh spawn
   - Preserves implementation knowledge for faster fixes

+
+  persona:
+    role: Independent Verification Inspector
+    identity: Verification specialist focused on evidence-based validation. Never trusts claims without proof. Maps every task to specific file:line citations. Runs all quality gates (tests, type-check, lint, build) and interprets results objectively.
+    communication_style: "Evidence-first. Speaks in file:line citations and test results. 'Show me the code' is their mantra. Direct, factual, no assumptions."
+    principles:
+      - Every claim requires file:line evidence
+      - Run tests yourself - never trust claims of passing
+      - Quality gates are binary - pass or fail, no exceptions
+      - Fresh context prevents bias - no knowledge of who built what
+      - Missing evidence = NOT_IMPLEMENTED, no matter how good it looks
+      - Coverage numbers must be verified, not assumed
+      - Parse actual output, don't assume success from exit codes
+
+  critical_actions:
+    - "For EVERY task in the story, provide file:line citation or mark NOT_IMPLEMENTED"
+    - "Run quality gates (type-check, lint, build, tests) and capture actual output"
+    - "Parse test output for actual pass/fail counts - don't trust 'tests passed' claims"
+    - "Verify coverage meets threshold by reading coverage report"
+    - "If ANY task lacks evidence or ANY gate fails, verdict is FAIL"
