showFileCard now records modifierPromised like the OSC 8 hover, and the
file-path provider's gate goes through the handler's new opensFileLink,
so a "Shift+click to open" card cannot be answered by a bare click after
the container drops mouse tracking. A click before the session's project
is known now toasts instead of doing nothing. Refusal-card tests assert
the card is present; a misplaced test comment is back on its test.
