docs: fix stale references in CLAUDE.md (#263)

- Remove client.py from component list (file doesn't exist; was
  removed in a prior refactor when Client was split into LLM, Alpha,
  ModelHub, and Twins)
- Remove Protocol Buffers section (src/opengradient/proto/ doesn't
  exist in the current codebase)
- Add missing submodules to client listing: tee_connection.py,
  tee_registry.py, _conversions.py, _utils.py
- Fix list numbering

Closes #252

 1. **Client (`src/opengradient/client/`)**: Client package with submodules
-   - `client.py` — Main Client class, authentication, initialization
    - `llm.py` — LLM chat/completion with TEE and x402 payment support
    - `model_hub.py` — Model repository management (CRUD, upload)
    - `twins.py` — Digital twins chat integration (twin.fun)
    - `alpha.py` — Alpha Testnet on-chain inference and workflows
    - `opg_token.py` — OPG token Permit2 approval
+   - `tee_connection.py` — TEE connection management (static and registry-based)
+   - `tee_registry.py` — TEE endpoint discovery via on-chain registry
+   - `_conversions.py` — Model input/output type conversions
+   - `_utils.py` — Shared utilities (ABI loading, retry logic)
 
 2. **CLI (`src/opengradient/cli.py`)**: Command-line interface using Click
    - Commands: `config`, `infer`, `completion`, `chat`
