Feature/memory pr (#894)

* feat: multi-turn context and conversation arc memory

PR 2E - Section 2.9, 2.10:
- Add multiTurnContext.ts with turn tracking and state preservation
- Add conversationArc.ts with goal/decision/milestone tracking
- Wire into query.ts after tool execution
- Feature-flags: MULTI_TURN_CONTEXT, CONVERSATION_ARC
- Add comprehensive tests (22 passing)

* feat(cli): add /knowledge command to manage native memory

- Add /knowledge enable <yes|no> to toggle Knowledge Graph learning\n- Add /knowledge clear to reset memory\n- Add persistent knowledgeGraphEnabled setting to global config\n- Integrated user setting into the query execution loop

* feat(cli): add /knowledge command (stable local-jsx version)

- Resolve conflicts between .ts and .tsx files\n- Align with LocalJSXCommandCall signature\n- Fix onDone and args errors

* test(cli): fix knowledge command tests by properly isolating global config

* fix(cli): make knowledge command defensive against undefined args and leaky tests

* fix(cli): correct data source for entity count and fix test isolation

* fix(cli): reinforce knowledge test by explicitly defining property on test config

* fix(cli): explicitly define property in test config to avoid undefined in CI

* fix(cli): make knowledge tests resistant to global config mocks in CI

* chore(memory): surgical improvements from architectural audit

- Fix: Implement entity deduplication in Knowledge Graph\n- Fix: Ensure fact extraction from user messages in query loop\n- Fix: Refine regexes for better quality learning (less noise)
