fix(mobile): show loading and syncing in the working pill

[juliusmarminge]

Mobile drew two different pills above the composer: the composer's own "Loading messages…" / "Syncing messages…" pill (bold text, tappable, no glass) and the floating "Working for …" timer pill (glass, merges with the scroll-to-end button). Opening a thread that was already working faded one out and the other in, with a different shape and font each time.

The floating working control now takes a status of either syncing (spinner + label) or working (timer), so both states render in the same element and the label just swaps in place. ThreadDetailScreen derives that status from the thread sync state and the active turn, with syncing taking priority. The composer's status pill now only reports connection problems (reconnecting, offline, error, not connected). The old sync pill's tap called reconnect, but since it only ever showed while already connected, nothing is lost by making the new one non-interactive.

Same gating as the timer had: hidden while disconnected or while an approval/user-input card owns the composer slot. The feed's bottom inset already keyed off the pill's presence, so it now reserves space during loading/syncing too.

Note

Low Risk
Mobile thread UI and status presentation only; no auth, data, or API changes. Feed inset logic already keyed off floating pill visibility, now extended to loading/syncing.

Overview
Thread loading and syncing now show in the same glass floating pill above the composer as the “Working for …” timer, instead of a separate bold composer status pill.

FloatingWorkingControl takes a status of syncing (spinner + “Loading/Syncing messages…”) or working (elapsed timer) so the label swaps in place without a second pill fading in. ThreadDetailScreen builds that status from thread sync + feed presentation, with syncing ahead of active work, and still hides the pill when disconnected or when approval/user-input owns the composer.

ThreadComposer drops threadSyncPhase and limits its status pill to connection problems (reconnecting, offline, error, not connected); when connected it shows nothing for sync.

Note

Show loading and syncing status in the floating working pill

• Moves message loading and synchronization status display from the composer connection pill to the floating working control pill on the thread detail screen.
• ThreadDetailScreen derives a floatingStatus from sync and content state, and passes it to FloatingWorkingControl. The floating pill now shows the sync label (with activity indicator) before showing the active-work timer.
• ThreadComposer and composerConnectionStatus no longer accept or produce a syncing status; the composer pill now reports only connection/retry states.
• Risk: ThreadComposerProps.threadSyncPhase is removed; any caller still passing it will get a type error. FloatingWorkingControl API changes from a nullable startedAt value to a nullable status object, requiring all callers to migrate.

Approvability

Verdict: Approved at 2317bdd

Macroscope's review found this PR approvable — This is a contained mobile UI fix that consolidates existing loading, syncing, and working indicators into one floating pill while preserving connection gating and existing timer behavior. No schema, data-processing, deployment, security, billing, or product-default changes are involved.
