chore(orion): tune buck2 and scorpio config

- Add BUCKD_STARTUP_TIMEOUT=30 and BUCKD_STARTUP_INIT_TIMEOUT to all
  buck2 command invocations (Buck2::command, get_repo_targets, build)
  to prevent daemon startup timeouts under slow I/O environments
- Bump scorpiofs dependency from 0.1.1 to 0.2.0
- Increase scorpio load_dir_depth from 3 to 5 and fetch_file_thread
  from 10 to 20 for better prefetch coverage and concurrency
