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.

## Summary
- replace the whole-tree file-size gate with a stateless differential
ratchet
- allow inherited files over 1,000 lines to hold or shrink, but never
grow
- delete the 44-entry numeric override ledger and run the same policy
across Desktop, Web, and Mobile CI
- fail closed when the local base cannot be resolved and cover policy,
Git status parsing, and base resolution in unit tests
This removes the shared mutable policy state that caused unrelated PRs
to fail after neighboring merges. It does **not** by itself prevent two
stale green PRs from becoming invalid when combined; that requires merge
queue or up-to-date branch enforcement.
### Related issue
None found. This follows the design discussion in the linked Buzz
channel.
### Testing
- `node --test scripts/check-file-sizes-core.test.mjs` (6/6)
- Desktop, Web, and Mobile ratchet entrypoints
- `just desktop-check`
- `just web-check`
- Mobile analysis
- `git diff --check`
The repository pre-push suite also exposed an unrelated existing Mobile
widget failure in `ChannelDetailPage keeps follow mode off while a tall
newest message stays visible`; it reproduces in isolation and this
branch does not touch Mobile widget behavior.
