[BUG] Help dialog cant be opened

[groutoutlook]

Description

• help_toggle uses ? in default-keybind.toml, but when pressing ?, the keybinding parser never matches and the help dialog never opens.

Environment

$ rustc --version
rustc 1.93.0 (254b59607 2026-01-19)

Steps to reproduce

0. Run the app.
1. Press ? (shift-/) from the main view.
2. Help dialog does not appear.

Expected behavior

• Pressing ? opens the help dialog.
  Instead, nothing happens because the key event lookup fails.

Solution

• Further reviewing can be done in PR.
