session-memory Phase 0: normalized schema (T01) + Claude adapter (T02)

- session_memory/core/schema.py: Session/SessionEvent/Cost dataclasses, flavor-prefixed uids, watermarks, kind/outcome validation (T01) - session_memory/adapters/claude.py: JSONL -> Normalized bundle, turn DAG via uuid/parentUuid, kind mapping, cost from message.usage (T02) - tests: schema round-trip + adapter (synthetic + real local session) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
