Mobile: combined fixes test branch (scroll, back-swipe, thread lists, computer switching)

[t3dotgg]

Note

Draft integration branch combining several in-flight mobile fixes for on-device testing. One commit per fix; not intended to merge as-is.

What Changed

All changes scoped to apps/mobile/ (plus one dependency bump):

• Fix thread scroll jump after send — dismiss the keyboard before the anchor scroll so a swallowed close event can't leave a phantom bottom inset; apply the RN 0.81 contentInset hit-test workaround so the blank area after a send is scrollable.
• Fix dead far-left-edge back swipe — remove the legacy thread navigation drawer and its left-edge pan gesture, which stole edge touches from the native back-swipe recognizer. The drawer was unreachable dead code from the old sheet-based routing.
• Quick new-thread button per project — pencil button in each Home project group header that opens the new-task draft pre-targeted to that project.
• Recent-threads window on Home — project groups default to threads from the last 5 days (or the 3 most recent), integrated with the existing Show more/less pagination.
• Stable timestamps — sub-minute times render as <1m instead of a ticking seconds counter; fixed-width timestamp column to stop layout shifts.
• Fix silent computer-switch failure — the machine picker only offers environments hosting the selected repository, so switching computers keeps the same repo instead of silently picking the first project.
• Bigger new-task composer text — headline type role (18pt, Dynamic Type-aware) instead of body.
• Bump react-native-keyboard-controller 1.21.6 → 1.21.13 — the app was below @legendapp/list's required 1.21.7; includes upstream fixes for non-scrollable chat scroll views with large blank space. Needs a fresh native build.

Checklist

• This PR is small and focused (combined test branch by design)
• I explained what changed and why
• Screenshots/videos pending device testing

Note

Medium Risk
Touches core navigation, keyboard/scroll timing, and new-task environment selection; changes are localized to mobile UI with added tests but need on-device validation.

Overview
Bundles several mobile UX fixes: thread detail no longer uses the slide-out ThreadNavigationDrawer or its left-edge pan (which blocked native back-swipe); compact thread routes without stack history get a Home header button instead.

After send, ThreadDetailScreen waits for KeyboardController.dismiss() before anchor scroll to avoid a stuck bottom inset; ThreadFeed enables the RN contentInset hit-test workaround so the blank area below the last message is scrollable. react-native-keyboard-controller is bumped to 1.21.13.

Home project groups now default to a 5-day recency window (or the 3 newest threads), with Show more/less tied to that baseline; search still shows full history. Group headers gain a + action (single real project only) that opens NewTaskDraft pre-scoped to that project.

New-task flow filters the machine picker to environments that host the selected repo and remaps the project when switching machines. Composer prompt uses headline typography; relativeTime shows <1m with a fixed-width timestamp column to stop row jitter.

Note

Fix scroll, back-swipe, and thread list behavior in mobile app

• Removes the thread navigation drawer and replaces it with a Home button in the header for compact layouts without navigation history (ThreadRouteScreen.tsx)
• Fixes a stuck bottom inset after sending a message by waiting for keyboard dismissal via KeyboardController.dismiss before scrolling to anchor (ThreadDetailScreen.tsx)
• Scopes the environment picker in the new-task flow to machines that host the selected repository, and preserves the same repository when switching environments (new-task-flow-provider.tsx)
• Home list groups now baseline on recent threads (5-day window, fallback to 3) per project; show-more/show-less compares against this baseline rather than a global constant
• Adds a plus button to single-project group headers in the home list to quickly create a new thread scoped to that project
• Changes relativeTime output under one minute from 'now'/seconds to '<1m' to reduce timestamp layout jitter

Approvability

Verdict: Needs human review

1 blocking correctness issue found. This PR introduces multiple runtime behavioral changes (thread recency filtering, environment switching, removed drawer navigation) and has an unresolved review comment about a missing collapse/expand chevron indicator. The scope and the identified UX bug warrant human review.

ThreadListGroupHeader no longer renders the collapse/expand chevron. The old chevron.right/chevron.down glyph was removed and replaced only by the plus new-thread button (or a blank spacer when onNewThread is absent), so every project header gives no visual indication of its collapsed state and looks non-collapsible. Consider restoring the disclosure chevron inside the toggle Pressable so the expanded/collapsed state is visible again.

Intentional — the disclosure chevron was removed at the maintainer's request; tapping the project title row toggles collapse. Declining this one.
