Log Message:
SyncTERM: add filtered Wren hook variants (C-side match)

Hook.onKey(key, fn), Hook.onInput(byte, fn), Hook.onMouse(event, fn)
register a callable that fires only when the event's discriminator
matches. The match check is in the C dispatcher: filtered entries
whose filter != value are skipped before any Wren slot is touched, so
the per-event hot path stays cheap.

Filtered and unfiltered hooks share one per-event array
(struct wren_hook_entry { fn, filter, filtered }), preserving
registration order across both forms.
