feat: implement ZCLAW Agent Intelligence Evolution Phase 1-3
Phase 1: Persistent Memory + Identity Dynamic Evolution - agent-memory.ts: MemoryManager with localStorage persistence, keyword search, deduplication, importance scoring, pruning, markdown export - agent-identity.ts: AgentIdentityManager with per-agent SOUL/AGENTS/USER.md, change proposals with approval workflow, snapshot rollback - memory-extractor.ts: Rule-based conversation memory extraction (Phase 1), LLM extraction prompt ready for Phase 2 - MemoryPanel.tsx: Memory browsing UI with search, type filter, delete, export (integrated as 4th tab in RightPanel) Phase 2: Context Governance - context-compactor.ts: Token estimation, threshold monitoring (soft/hard), memory flush before compaction, rule-based summarization - chatStore integration: auto-compact when approaching token limits Phase 3: Proactive Intelligence + Self-Reflection - heartbeat-engine.ts: Periodic checks (pending tasks, memory health, idle greeting), quiet hours, proactivity levels (silent/light/standard/autonomous) - reflection-engine.ts: Pattern analysis from memory corpus, improvement suggestions, identity change proposals, meta-memory creation Chat Flow Integration (chatStore.ts): - Pre-send: context compaction check -> memory search -> identity system prompt injection - Post-complete: async memory extraction -> reflection conversation tracking -> auto-trigger reflection Tests: 274 passing across 12 test files - agent-memory.test.ts: 42 tests - context-compactor.test.ts: 23 tests - heartbeat-reflection.test.ts: 28 tests - chatStore.test.ts: 11 tests (no regressions) Refs: ZCLAW_AGENT_INTELLIGENCE_EVOLUTION.md updated with implementation progress
