bug(tui): Keyboard shortcuts don’t work while Zhuyin ((tranditional) IME is active on macOS (Ghostty) #13805

Description

On macOS, when the input source is Zhuyin (tranditional), most/all keyboard shortcuts inside OpenCode TUI stop working. Only Ctrl+C still works (interrupt). Switching the macOS input source to English (ABC) immediately restores all shortcuts.

This seems related to #8652 (Korean IME on macOS), but for Zhuyin(tranditional)

Expected behavior

Shortcuts should work regardless of active input source / IME.

Actual behavior

Shortcuts are ignored while Zhuyin IME is active; only Ctrl+C works.

Additional notes / diagnostics

In the same Ghostty session, running cat shows Ctrl sequences can reach the child process (e.g. ^P is received). This suggests the terminal/PTY can deliver control characters, but OpenCode TUI does not handle shortcuts while IME is active.

try bunx opencode-ai@snapshot-kmdr-debug, still not work.

Plugins

no

OpenCode version

1.2.1

Steps to reproduce

1. Switch macOS input source to Zhuyin (tranditional)
2. Launch opencode (TUI)
3. Try common shortcuts (e.g. Ctrl+P, Ctrl+X leader shortcuts, etc.)
4. Observe nothing happens
5. Switch input source to English (ABC)
6. Try the same shortcuts again → works
