Scheduling tools and the two remaining request_* tools fell through to
fmtArgsGeneric. They already had appropriate icons (⏱️ / 📦) but the
arg display was multi-field verbose.
New fmtToolUse cases:
- request_init_config: 'request_init_config* iris'
- request_update_meta_inputs: 'request_update_meta_inputs* [nixpkgs, …]'
(or 'all' when inputs list is empty)
- list_schedules: 'list_schedules*()' (no args, explicit)
- cancel_schedule: 'cancel_schedule* #42 all' or '#42 [iris, dmatrix]'
- fire_schedule_now: 'fire_schedule_now* #42'
- edit_schedule: 'edit_schedule* #42 · body · interval · +2 tgt'
(lists which fields are being changed, not their values)
- request_schedule_prompt: 'request_schedule_prompt* → iris at 14:00Z +3600s'
Closes#2201
