* Refactor sub-agent architecture and introduce async support
- Removed the legacy subagent.yaml file and replaced it with individual YAML files for each sub-agent in the subagents directory.
- Updated the load_subagents function to support both directory and single file layouts for loading sub-agent configurations.
- Added new langgraph_dev module for managing async sub-agent lifecycle and deployment.
- Created graphs for async sub-agents (writing-agent, data-analysis-agent) and updated langgraph.json for deployment.
- Introduced new sub-agent definitions for planner, research, debug, code, and writing agents with appropriate system prompts and configurations.
- Enhanced package data inclusion in pyproject.toml to accommodate new sub-agent YAML files.
* Refactor code for improved readability by consolidating conditional statements and formatting
* feat: enhance async sub-agent support with workspace synchronization and user feedback
- Added console status messages during async sub-agent server startup and workspace synchronization to improve user experience.
- Implemented a new WorkspaceSyncWidget for live feedback during workspace sync operations.
- Updated onboarding to reject occupied ports and ensure proper workspace handling for async sub-agents.
- Introduced locking mechanisms to manage concurrent access to langgraph dev processes and workspace states.
* feat: add async sub-agent configuration and server management functions
* feat: improve port occupation handling and log file management in start_langgraph_dev
* feat: enhance async sub-agent handling and introduce comprehensive tests
- Updated `_maybe_swap_async_subagents` to improve async sub-agent management, ensuring internal flags are stripped before handoff.
- Enhanced port management in `onboard.py` to allow reuse of occupied ports if already running by the same service.
- Introduced file locking in `manager.py` to prevent race conditions during concurrent CLI invocations.
- Added new tests for async sub-agent swapping and langgraph manager functionalities to ensure reliability and correctness.
- Updated dependencies in `pyproject.toml` to include `psutil` and `filelock`.
* fix(docs): clarify sub-agent configuration in README
* test(manager): isolate _PID_DIR + tighten reuse-path assertion
Addresses CodeRabbit review on tests/test_langgraph_manager.py:
- Patch _PID_DIR to tmp_path so the FileLock setup in
ensure_langgraph_dev doesn't mkdir the user's real
~/.config/evoscientist/ dir as a test side-effect.
- Tighten "result is None or hasattr(result, 'poll')" to a strict
"result is None" — the reuse path returns None unconditionally,
so the OR clause was hiding potential regressions.
