Bug: TUI leaves focus reporting (ANSI ?1004h) enabled after exit, causing iTerm2 repeated warning on every new shell. Environment: kiro-cli 2.6.1, macOS ARM64, iTerm2 3.6.11, zsh. The tui.js component enables focus/mouse reporting but does not reliably dis

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 26.5.1 (25F80)

Expected behaviour

When kiro-cli chat session exits or shell integration hooks run, all terminal modes enabled by kiro-cli (including focus reporting \e[?1004h) should be properly disabled (\e[?1004l). New shell sessions should start with a clean terminal state.

Actual behaviour

Focus reporting mode remains enabled after kiro-cli exits. iTerm2 3.6.x detects this orphaned terminal state and displays a warning banner on every new shell/tab: "Looks like focus reporting was left on when an ssh session ended unexpectedly or an app misbehaved. Turn it off?"

Steps to reproduce

1. Install kiro-cli 2.6.1 with shell integration enabled (zshrc.pre.zsh / zshrc.post.zsh hooks active)
2. Use iTerm2 3.6.11 on macOS
3. Open a new terminal tab or window
4. Wait a few seconds — the focus reporting warning banner appears
5. Repeat: open another new tab — same warning appears again
