docs(README): update architecture diagram to v2.0 reality

- Add Wire Watcher, StructuringWorker, Codebase Analyzer
- Separate Ingestion / Processing / Storage / Interfaces layers
- Add MCP Server (15 tools) and MCP Clients
- Add PROJECT.md / AGENTS.md generation
- Fix data flow: extractor -> queue -> worker -> structured store
- Update component table with all 12 components

 |-----------|---------|
 | **Hooks** | 7 lifecycle event handlers (SessionStart, PostToolUse, SessionEnd, PreCompact, PostCompact, etc.) |
 | **Plugin** | 3 AI-callable tools: `mneme_search`, `mneme_timeline`, `mneme_get` |
-| **Extractor** | Parses observations, detects truncation, creates checkpoints, detects patterns |
-| **Compressor** | Generates semantic summaries via configurable LLM (Kimi API, Ollama, OpenAI-compatible) |
-| **Injector** | Injects checkpoints, patterns, and relevant past context at session start |
-| **SQLite** | Stores sessions, observations, summaries, checkpoints, patterns, compaction events |
-| **sqlite-vec** | SQLite extension for semantic similarity search (primary, cross-platform) |
-| **Web Server** | FastAPI-based API on port 37777 — real-time SSE event stream |
+| **Wire Watcher** | watchdog-based indexing of Kimi CLI `wire.jsonl` + `state.json` |
+| **Extractor** | Sanitizes observations, adds to pending queue, creates checkpoints, detects patterns |
+| **StructuringWorker** | Background worker: AI structuring (Kimi/Ollama/OpenAI) → heuristic fallback |
+| **Compressor** | Generates session summaries via configurable LLM |
+| **Injector** | Injects structured context + semantic search results at session start |
+| **Codebase Analyzer** | Tree-sitter AST analysis (Python, JS, TS, Rust, Go) — scan, search, outline |
+| **SQLite** | Raw observations, structured observations, vectors, collections, wire events |
+| **sqlite-vec** | 384-dim embeddings for semantic similarity search (primary, cross-platform) |
+| **Web Server** | FastAPI + vanilla JS on port 37777 — SSE stream, structured cards, search |
+| **MCP Server** | 15 tools for Claude Desktop, Cursor, Goose — search, timeline, collections, codebase |
