v0.2.0: Plug-and-play — dual transport (stdio+HTTP), AYON 1.15.4 compat, Dockerfile

- client.py: add verify=False for internal/self-signed SSL, catch 404
  on list_products() and get_last_version() (AYON >=1.15 compat)
- server.py: dual transport via AYON_TRANSPORT env (stdio default,
  http for Docker); uvicorn for HTTP mode
- pyproject.toml: bump to 0.2.0, add uvicorn dep, remove ayon-python-api
- README: full docs with Claude Desktop/Cursor/Hermes/Docker configs
- Dockerfile: multi-layer build, pip install from pyproject.toml
- .dockerignore: exclude venv, cache, dist

 AYON REST API (/api/projects, /api/products, ...)
 ```
 
+The MCP server is the **only gatekeeper** to AYON. All product types
+(`imageMain`, `modelMain`) and naming conventions are enforced server-side.
+The AI agent orchestrates the workflow but never touches raw API calls.
+
+### Dual transport: stdio + HTTP
+
+- **stdio** (default): `AYON_TRANSPORT=stdio` or unset. The MCP server communicates
+  over stdin/stdout — required for Claude Desktop and Cursor.
+- **HTTP**: `AYON_TRANSPORT=http`. Listens on `PORT` (default 8000). Use for
+  Docker deployments or when the MCP server runs on a different host than the agent.
+
+The same binary serves both modes — no separate builds needed.
+
+## Compatibility
+
+| Feature | AYON ≥1.15 | Older AYON |
+|---------|-----------|------------|
+| List projects | ✅ | ✅ |
+| List folders | ✅ | ✅ |
+| Create product | ✅ | ✅ |
+| Create version | ✅ | ✅ |
+| Create representation | ✅ | ✅ |
+| List products (read-back) | ⚠️ falls back gracefully | ✅ |
+| Get last version | ⚠️ falls back gracefully | ✅ |
+
+AYON ≥1.15 removed the REST endpoints for listing products and versions.
+The MCP server catches 404 and returns empty results — publish still works,
+but read-back requires the GraphQL endpoint (not yet implemented in the MCP
+tools).
+
 ## Limitations
 
 - **REST-only**: Products are registered as metadata. Actual file upload into
   project anatomy requires the pyblish pipeline (DCC host).
 - **No folder creation**: Folders must exist before publishing. Use AYON Web UI
-  or Tray Publisher to create them first.
+  or Tray Publisher to create them first, or create them via REST API.
 - **Representations are metadata**: The `files` array contains names/sizes,
   not uploaded content. Full file publishing needs a host with pyblish.
