feat: add LiteLLM gateway scaffold and dashboard health probe

Introduce a localhost-only LiteLLM service template and expose a protected dashboard health endpoint for operational visibility, while adding cc-connect mobile bridge templates with conservative defaults.

+# cc-connect (Phase 1)
+
+Mobile bridge service for interacting with coding agents through chat, with LiteLLM as model gateway.
+
+## Scope
+- LiteLLM remains the unified cloud-model endpoint.
+- cc-connect remains the chat/mobile bridge.
+- Start with a single platform (Discord) for lower operational risk.
+
+## Files
+- `config.example.toml`: non-secret template.
+- `docker-compose.yml`: optional always-on service shape.
+
+## Setup (NAS)
+1. Copy template and fill secrets locally:
+   - `cp cc-connect/config.example.toml cc-connect/config.toml`
+   - create `cc-connect/.env` with platform token(s)
+2. Keep secrets local only (`.env` is gitignored).
+3. Start service:
+   - `docker compose -f cc-connect/docker-compose.yml up -d`
+
+## Security defaults
+- Single platform enabled.
+- Confirm/permission-gated command mode.
+- Keep shell/file-write capabilities disabled initially.
+- Restrict users/channels with explicit allowlists.
+
+## Notes
+- This repo only includes templates and orchestration shape.
+- Exact runtime keys/fields can vary by cc-connect release; adjust `config.toml` to your installed version.
