* feat(deploy): implement standalone LangGraph server and CLI command for deployment
* feat(deploy): enhance port validation and environment variable management for deployment
* Refactor langgraph dev deployment and introduce workspace sidecar protocol
- Updated the deployment mode handling in `server.py` to use a single environment variable `EVOSCIENTIST_DEPLOY_MODE` with values `full` and `stripped`.
- Enhanced the `manager.py` to implement a workspace fingerprint sidecar, allowing cross-process reuse of langgraph dev instances while ensuring workspace consistency.
- Introduced functions to write and read the workspace sidecar, with error handling for missing or corrupt data.
- Added tests for the workspace sidecar functionality, including validation of the JSON schema and ensuring proper error handling for workspace mismatches.
- Updated existing tests to reflect changes in deployment mode handling and added new tests for signal handling during shutdown.
- Ensured that cleanup routines remove the workspace sidecar alongside the PID file during shutdown.
* fix(langgraph): improve workspace sidecar checks for process ownership and stale handles
