feat(container): add Docker deployment and terminal shell fallback (#520)

* feat(container): add Docker deployment and terminal shell fallback

Add Docker runtime assets (Dockerfile, compose file, and entrypoint) to run OpenChamber in containers with persistent config/data mounts.

Improve terminal PTY startup reliability by probing multiple shell candidates and falling back automatically across Unix and Windows environments.

* fix: add OMO install env

* docs: add Docker Compose instructions to README

+### Docker Compose
+
+```bash
+docker compose up -d
+```
+
+The service will be available at `http://localhost:3000`.
+
+**Data Directory Permission Note:** The `data/` directory is mounted into the container for persistent storage (config, sessions, SSH keys, workspaces). Before running, ensure the directory exists and has proper permissions:
+
+```bash
+# Create data directories with correct ownership
+mkdir -p data/openchamber data/opencode/share data/opencode/config data/ssh data/workspaces
+
+# Fix permissions (replace $USER with your username)
+chown -R 1000:1000 data/
+```
+
+Without proper permissions, the container may fail to start or encounter permission denied errors when writing to these directories.
