Problem Statement

Summary

claude agents quits only via double Esc, whereas a normal Claude Code session (including claude --resume) quits via Ctrl+D, Ctrl+D. The two views use different exit gestures, which breaks muscle memory. claude agents should also accept Ctrl+D, Ctrl+D to exit, in addition to the existing double-Esc.

Motivation

• Inconsistent exit keys across views: claude --resume / normal sessions exit on Ctrl+D, Ctrl+D, but claude agents ignores it and only exits on double Esc.
• Users habitually press Ctrl+D, Ctrl+D to leave a Claude Code screen; in claude agents this does nothing, which is confusing and makes the view feel like it "won't quit."
• Matching the established exit gesture makes the TUI behave predictably regardless of which view you're in.

Proposed Solution

In claude agents:

1. Accept Ctrl+D, Ctrl+D to exit the view, behaving identically to how it exits a normal claude / claude --resume session.
2. Keep double Esc working as well — this is additive, not a replacement.
3. Both gestures should perform the same clean exit of the agents view.
