feat(P03): core agent flesh — VerifierAgent, ResearcherAgent, TesterAgent intrinsic logic

---ci---
phase: 2
milestone: v0.6
status: execute
decisions:
  - id: D-001
    decision: Pass GitAgentContext to agents instead of bare AgentContext
    rationale: Agents need git-native context (gitContext, gitBranch, ciFiles, milestone) to operate autonomously
    confidence: 0.95
  - id: D-002
    decision: Implement multi-phase iteration with totalPhases derived from ROADMAP.md
    rationale: Milestones can span multiple phases; orchestrator must advance through all of them
    confidence: 0.90
  - id: D-003
    decision: Add executeStageWithRecovery with retry + plan revision + escalation
    rationale: Robust error recovery requires multiple fallback levels before giving up
    confidence: 0.85
  - id: D-004
    decision: Add timer-to-escalation mapping in EscalationProtocol for proper cleanup
    rationale: resolveEscalation must clearTimeout for the corresponding timer to prevent resource leaks
    confidence: 0.90
  - id: D-005
    decision: Add dispose() to EscalationProtocol called in orchestrator finally block
    rationale: Ensures all timers are cleaned up on orchestrator exit regardless of outcome
    confidence: 0.95
  - id: D-006
    decision: Add mechanical TEST stage fallback running npm test via execSync
    rationale: When no backend is available, tests can still be run mechanically
    confidence: 0.85
