Quick Mode Overlay (M2 #6)

[ddroid]

What to build

Implement ronin --quick as a compact, centered, overlay-style window for one-shot questions. Quick mode should feel like a launcher-style AI surface — fast to open, fast to answer, fast to dismiss.

The user types a question, gets a streamed answer, and can then:

• Copy the answer
• Save the exchange to a full thread
• Open the full thread in the main window

Quick mode must support both light and dark themes and respect the system theme preference.

Acceptance criteria

• ronin --quick opens a compact overlay-style window (not the full app shell)
• Quick mode window is centered on screen with a focused, minimal layout
• User can type a question and receive a streamed response
• User can copy the answer to clipboard
• User can save the exchange to a new or existing thread
• User can open the saved thread in the main Ronin window
• Esc dismisses the quick mode window
• Quick mode respects the configured theme (light/dark/system)
• Quick mode works with single-instance routing (sends intent to running instance if one exists)
• Quick mode feels fast — window appears near-instantly
