fix(shortcuts): handle command palette in terminal

[janburzinski]

Description

on windows when you were tabbed in in a terminal the ctrl+k keybind didnt work since xterm swallowed it, this should fix it and make it work on all platforms.

• only intercepts explicitly allowlisted shortcuts (shortcut-registry)

Greptile Summary

This PR makes app shortcuts work while an xterm terminal is focused. The main changes are:

• Adds a terminal keyboard bridge mounted in the workspace.
• Dispatches only shortcuts marked with overrideTerminalFocus.
• Prevents handled terminal-focused shortcuts from reaching xterm or the normal bubbling listener.
• Adds browser tests for terminal focus, duplicate registrations, and non-allowlisted keys.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
