[BUG] Quick Entry "double-tap Option" fires while typing accented characters (macOS, international layouts)

What's Wrong?

On macOS keyboard layouts where Option composes diacritics (Polish, German, Spanish, French), the default Quick Entry shortcut "double-tap Option" false-positives during normal typing.

Typing two Option-composed characters in quick succession - e.g. Option+A then Option+L for "ał" - is counted as a bare double-tap of Option, and the Quick Entry overlay opens mid-word and steals focus from whatever app I'm typing in.

The detector appears to count raw Option keydown/keyup events without checking whether Option was used as a modifier.

Note: this is the Claude Desktop app's global Quick Entry hotkey, not the CLI.

What Should Happen?

An Option press should only count toward the double-tap if no other key was pressed while Option was held down (keydown → keyup with nothing in between).

Typing "ał" should type "ał" and leave the overlay closed.

Error Messages/Logs

Steps to Reproduce

1. macOS, input source set to "Polish Pro" (any Option-composed layout works: German, Spanish, French).
2. Claude Desktop, Quick Entry enabled, Quick access shortcut = "Double-tap Option" (default).
3. In any text field outside Claude, type a word with two Option-composed characters in quick succession, e.g. "chciałabym" → Option+A, then Option+L.

Result: the Quick Entry overlay opens.

• #82156 — macOS global-shortcut collisions; notes that disabling the Quick Access shortcut only reduced, not eliminated, unintended triggers.
• #66507 — ESC during IME composition cancels a running task; same class of problem, shortcut detection ignoring that the key is being used for text input.
• #88142, #18221 — Option/Alt on international layouts, but both about the CLI.
