Fix watch command stdout buffering#43

Conversation
The watch command was not producing any output because stdout was not being flushed after printing JSON lines. This caused the watch functionality to appear broken even though message detection was working correctly. Added fflush(stdout) call after Swift.print() to ensure immediate output delivery, fixing both CLI watch mode and RPC watch notifications. Fixes: Messages detected but not displayed Testing: Verified with 'imsg watch --chat-id 1 --json' - messages now appear immediately
