Fix: scope terminal event handler to setup terminals only

The onEvent handler unconditionally called ensureTerminal and
setTerminalLaunchContext for every started/restarted terminal event,
not just server-initiated setup terminals. This caused the drawer to
force-open for all terminal events and set worktreePath: null for
non-setup terminals, creating stale launch context entries that the
ChatView cleanup effect could not clear.

Guard the handler to only fire for setup terminals (IDs starting with
'setup-'), and since we now know it's a setup terminal, always use
event.snapshot.cwd as the worktreePath instead of conditionally
returning null.
