klopez4212 85edc0572a feat(mobile): desktop-parity emoji and thread experience (#3485)
Brings the Flutter app's emoji and thread surfaces up to desktop parity.

## Emoji

- **Full emoji-mart dataset** generated from the same `@emoji-mart/data`
set desktop uses (1,870 emoji, 8 categories), committed as an asset — so
shortcodes, names, and keywords are identical across clients. `just
mobile-emoji-data` regenerates it.
- **Rebuilt the tray**: search (a Dart port of desktop's tiered
`emojiSearch` ranking, extended to names and keywords), a
frequently-used section, and one continuous scroll with pinned section
headers. The category rail is a shortcut into that list, not a page
switcher, and spans the full width the search field uses. Custom emoji
share the native glyph size and cell.
- **Reaction pills** match desktop's geometry, and the count shows at 1.
- **Emoji-only messages** render at 36px with 1.45em inline custom
emoji, matching desktop's `emojiOnly` treatment.
- **Positive-emoji burst** ported from desktop's `EmojiBurstProvider`,
suppressed under reduced motion.

## Threads

- **Top-down layout** — head first under the app bar, replies flowing
down, like desktop's thread panel. The old reversed list bottom-anchored
the content and jammed the head against the composer.
- **Tap a channel message to open its thread**; long-press still opens
the action sheet.
- **Live reactions.** The thread's relay query is one-shot and its
`kinds` filter carries only content rows, so a reaction event could not
reach an open thread at all, and `allMessages` was a snapshot frozen
when the route was pushed — a new pill only appeared after leaving and
re-entering, which refetched. The live channel events are now unioned
into the thread's list. The burst is also route-guarded, since the
channel timeline stays mounted underneath and was claiming it first.
- The `+` affordance follows the channel: replies stay bare until they
carry a reaction, and the head keeps a standing `+`.

## Keyboard

A deliberate downward drag past ~48px dismisses the keyboard; short
scrolls leave it alone. Applies to the channel list, the thread list,
and the compose bar (via a raw `Listener`, so it can't steal the field's
tap or selection drags).

True finger-tracking dismissal is out of scope — Flutter only offers
`manual`/`onDrag`, and 1:1 tracking needs a native `UIScrollView` proxy
plus Android's `WindowInsetsAnimationController`.

## Testing

`just mobile-check` and `just mobile-test` pass (965 tests). New
coverage for emoji search ranking, dataset parsing, the emoji-only
predicate, tray scroll/rail behavior, reaction pills and the burst, and
both thread fixes above. `just ci` green.
