timeout for trigger sequences

[fabolous005]

When using trigger sequences to (for example) resize a split, we would have to press the trigger everytime before the keystroke for the relative action.

It would be super convenient to have a timeout that defines for how long the trigger is valid, where the timeout would be refreshed when a keystroke is received or turned off once the timeout is reached.

This would allow resizing with trigger sequence by just triggering once and holding the keycombination for the resize action.

I realize that this has a very small usecase, as it's only truly relevant for these actions:

• resize_split
• next_tab/last_tab
• increase_font_size/decrease_font_size
• adjust_selection
• jump_to_prompt

but maybe this is something to think about for the future when ghostty is a little more stable and sure in which direction it is going...
What do you think?

I think this is relevant to another discussion that is discussing "persistent" key sequences or I think they're called "key tables" or something. Where pressing a prefix actives the table and it must be explicitly exited.
