Audit follow-up — the toggle behaviour now lives in a single
`ToggleableTimeAgoText` core in `ui/note/elements/TimeAgo.kt`. `TimeAgo`,
`NormalTimeAgo`, `ChatTimeAgo`, and `ChatroomHeaderCompose.TimeAgo` are
thin wrappers that pick a `TimeAgoStyle` (Dotted / Short) and pass
colour/font params; no per-site duplication of state + clickable +
derivedStateOf.
Performance fixes that matter for a feed with hundreds of timestamps:
- `rememberSaveable` → `remember`. Persisting a transient peek-toggle to
the SavedStateRegistry for every visible+scrolled-past note was pure
memory bloat. Recycling now resets to relative, which is the expected
behaviour for a transient inspect action.
- The relative-mode `derivedStateOf` lambda reads `nowState.value` only
when displaying a relative time. An item the user has frozen to its
absolute date no longer re-evaluates every 30-second tick.
- Core composable takes only stable primitive params (Long, Color,
TextUnit, TextOverflow, enum) so Compose can skip it entirely when
inputs don't change.
- Desktop wrapper dropped the redundant `derivedStateOf`: its formatter
reads no State, so derivedStateOf had nothing to observe.
