chore: remove stray screenshot and harden daemon getCwd test

- drop orca-before-split.png accidentally committed in the Wip commit
- accept null OR string from getCwd in the daemon test, since the new
  terminal-host fallback calls resolveProcessCwd(pid) and the mock pid
  55555 could resolve against a live process on CI
