feat: deliver hidden terminal output to daemon clients

[parsakhaz]

Summary

• add a daemon-only event sink to the runtime so Electron-visible delivery and daemon delivery can diverge where needed
• keep visible terminal output on the existing fanout path while sending hidden terminal output only to daemon subscribers
• add focused terminal manager regression coverage for visible vs hidden output delivery

Testing

• pnpm typecheck
• pnpm lint
• CI=1 pnpm --filter main test
• PANE_DIR=/tmp/pane-phase2-daemon-terminal-hidden-delivery xvfb-run -a pnpm test:ci
