fix(tools): auto-create work directory if missing in production

Added logic to create botserver-stack/data/system/work directory
if it doesn't exist. This ensures production deployments work
without manual directory setup.

Changes:
- Added fs::create_dir_all() in use_tool.rs
- Added fs::create_dir_all() in tool_context.rs
- Logs when directory is created
- Fixes production deployment where /system/work may not exist

This ensures the tool loading works in fresh production environments
where the work folder hasn't been populated yet.
