fix: resolve spawn python ENOENT error on Linux by using getAugmentedEnv() (#281)

- Use getAugmentedEnv() in project-context-handlers.ts to ensure Python is in PATH
- Add /usr/bin and /usr/sbin to Linux paths in env-utils.ts for system Python
- Fixes GUI-launched apps not inheriting shell environment on Ubuntu 24.04

Fixes #215
