refactor: make executable resolution async and centralize spawn

Browse Source 
- Rename findExecutable → findExecutableSync, add async findExecutable
  that uses promisified execFile instead of execFileSync
- Simplify Windows PATH resolution: rely on inherited env from Explorer
  instead of shelling out to PowerShell for registry PATH entries
- Add spawnProcess() helper that centralizes Windows shell/quoting concerns
- Update all agent providers and consumers to use async executable resolution
- Add windowsHide: true across all Windows child process calls
