…n isolation
- Add sessionId parameter to read_context, update_context, cleanup_context tools
- Add session ID validation (alphanumeric + hyphens, 1-64 chars) to prevent path traversal
- Route to session-specific files (sessions/ctx-{sessionId}.md) when sessionId provided
- Preserve backward compatibility: no sessionId = legacy context.md behavior
- Add types: CONTEXT_SESSIONS_DIR, SHARED_DECISIONS_PATH, isValidSessionId(), getSessionContextFilePath()
- Add sessionId to ResetContextData, AppendContextData, ContextReadOptions interfaces
- 14 new tests covering session routing, validation, isolation, and backward compatibility
Closes #843
