feat: add Anthropic Messages API + refactor server into clean handlers

Feat: Anthropic compatible
- Add POST /v1/messages and /messages endpoints
- Full SSE streaming (content_block_start/delta/stop + message_start/delta/stop)
- Tool use blocks with input_json_delta streaming
- Thinking blocks mapped to Anthropic format
- Anthropic messages -> CC wire format conversion

Refactor: server code split
- server_controller.dart: HTTP server, routing, shared endpoints
- openai_handler.dart: OpenAI-compatible handler
- anthropic_handler.dart: Anthropic-compatible handler
- Removed diagnostic/debug logging, production-level only

Docs: split README into docs/
- README.md trimmed to preview; details moved to docs/
- New: INSTALL.md, API-REFERENCE.md, TUI.md, ARCHITECTURE.md
- API-REFERENCE.md covers OpenCode, Zed client configs
- AGENTS.md synced with new file structure

 ## Auth
 
-Command Code auth is stored at `~/.commandcode/auth.json`. The bridge reads the API key from this file. Run `cmd login` to authenticate first. You can also press `[l]` in the bridge TUI for login instructions.

 ## Architecture
 
 ### Stack
 - Language: Dart 3.10+
 - TUI: `nocterm` v0.8.0 (ProgressBar for visualizations)
 - Server: `dart:io` `HttpServer`
-- HTTP client: `package:http`
+- HTTP client: `dart:io` `HttpClient`
 - Compile: `dart compile exe` -> single binary
 - Distribution: npm tarball with Node.js launcher wrapper

+## v1.1.0 (unreleased)
+
+### Features
+
+- Anthropic-compatible Messages API (`/v1/messages` and `/messages`)
+  - Full SSE streaming: content_block_start/delta/stop + message_start/delta/stop
+  - Tool use blocks with input_json_delta streaming
+  - Thinking blocks (reasoning mapped to Anthropic format)
+  - Non-streaming endpoint with proper Anthropic response shape
+  - Anthropic Messages protocol -> CC wire format conversion (system, tools, messages)
+  - stop_reason mapping: tool-calls -> tool_use, length -> max_tokens
+
+### Refactor
+
+- Server code split into three clean files:
+  - `server_controller.dart` — HTTP server, request routing, shared endpoints (/models, /health, /token, /info)
+  - `openai_handler.dart` — OpenAI-compatible handler (streaming + non-streaming)
+  - `anthropic_handler.dart` — Anthropic-compatible handler (streaming + non-streaming)
+- Common upstream body builder shared between handlers
+- Removed diagnostic/debug logging; production-level logging only
+- Renamed ProxyServer -> ServerController, extracted handlers to own classes
+- Update OpenCode protocol mapping for production upstream format
+- Fixed config.date field missing from OpenAI handler (was broken after refactor)
+
+### Docs
+
+- README.md trimmed to preview; detailed docs moved to `docs/`
+- New docs: INSTALL.md, API-REFERENCE.md, TUI.md, ARCHITECTURE.md
+- API-REFERENCE.md covers OpenAI, Anthropic, and Zed client configurations
+- AGENTS.md synced with new file structure and endpoints
