swift: parity with upstream aacefcd7e9..a908a7ac87

[Bl4ckBl1zZ]

Brings the native iOS app (apps/swift-ios) up to the user-visible behavior that sync: upstream aacefcd7e9..a908a7ac87 (122 commits) (#402) added on web and Expo. One commit per feature.

Verification: xcodebuild build-for-testing (scheme T3Code, Debug, generic/platform=iOS Simulator, Xcode-beta, CODE_SIGNING_ALLOWED=NO) compiles the app and the T3CodeTests target at every commit. generate-swift-contract-fixtures.ts --check is up to date. Tests were not run locally (no simulator runs in this pass); the Native iOS CI job runs them.

Implemented

• a7223f3969 Restart continuations read "Sent by T3 Code". Agent-sent messages whose creationSource is server are attributed to T3 Code (no sender link), not to "another agent".
• 8c777fbfad Stop a Claude subagent without stopping its owner. Stop on a live Claude-native subagent sends subagent.stop to the owning thread. The gate matches web's canStopSubagent: Claude driver, a native task handle with an id, and a live task. T3-owned subagents still stop by interrupting their child thread.
• c572cb71d2 Subagent rows follow the child's live work. A resumed follow-up shows as running again, and a rolled-back child shows as interrupted.
• 477282263a Messages sent during worktree setup queue behind it instead of steering while the thread is preparing or starting.
• c727d1219f Compact-first follows Claude's real prompt cache TTL. It uses the newest usage report and the optional promptCacheTtlMs, with the 70-minute rule as the fallback for older servers.
• 0be20c86c2 + 716357cbba Usage limits. Accounts are keyed by email plus the optional workspaceId, so one email in two workspaces is two accounts. A report without a workspace joins its email's only workspace. Codex windows pool by kind. Antigravity's new quota groups stay together, Gemini first.
• 9b40d37463 + c3243f0508 PR actions and edits follow the host. List quick actions offer only what the host reports (older servers keep GitHub's set). Per-item canEdit, editChangeRequest and canResolve win where present; canResolve can only narrow.
• ec43786140 A reply that finished before a steer replaced it isn't folded away as partial. The fold reads "Cut off by a steer".
• 1cfd1c1a44 Toggling a fold at the bottom keeps you at the bottom. iOS had the same bug.
• a908a7ac87 Search finds threads by their branch PR (#n, owner/repo#n, or URL).
• 72fbad7b1a A new project's first thread starts in its folder, not a worktree, when the server-wide default is worktree.
• 0f36a11769 Diff line counts use one formatter with digit grouping everywhere.
• 2a4ee33982 Settings → Microphone. Rank wired, Bluetooth, built-in and CarPlay mics, plus remembered devices. Recording picks the first connected one.

Tests added: MicrophonePriorityTests, ThreadTimelineStructureTests, DailyUXSidebarTests, DailyUXNewTaskTests, ThreadRelationshipRowsTests, ComposerRequestsParityTests, ClaudeResumeCompactionTests, UsageLimitsMergeTests, PullRequestQuickActionTests, PullRequestEditingTests.

Skipped

• 02612c2856 (image-only task): already works on iOS.
• d404a30118 (iPad pairing QR): a React Native sheet remount bug; iOS has its own scanner.
• 57b3780770 (browser picture in picture): iOS has no browser preview stream.
• a1dee8b2b3, a2f4c7fb7c (usage reset icon, working pill bulge): the defects don't exist on iOS.
• 91474e56f6 (question auto-advance): iOS has no delay timer and re-checks the question before advancing.
• a70ee2a7a0 (Resume model): iOS has no manual-continuation Resume.
• 29e09df979, 0ecb25a8d4, d02e292610: web dialog and selection layout fixes. iOS uses a system alert, a full-screen viewer, and per-row selection.
• 477282263a auto-branch expectedEmpty: iOS only picks a branch at thread creation, never as an automatic default on an existing thread.
• a4c8745abe (publish new projects to GitLab): iOS has no "new project from a name" flow.
• a8bdfdb541 (Claude 5 task lists), subagent modelSelection, and oom_kill failures: already rendered correctly.
• run.delegatedTaskId, Pi usage history: no iOS screen reads them. Providers decode as strings, so nothing breaks.
• 0442f5bfcc (filesystem.getMetadata file icons): would need a client metadata cache for little phone benefit.
• 6c13016394 (thread links wait for a live shell): iOS already holds a thread request until the thread arrives.
• 7b09ac7e00 ("OpenCode Zen" label): iOS shows the sub-provider alone, so there's no duplication.
• Host-only or desktop-only: OpenTelemetry export settings, right-panel tab drag and maximize, keyboard shortcuts, Windows/macOS signing and packaging, annotation styles, settings width tweaks.

Decision log

• No capability gate on subagent Stop: the sync added none for subagent.stop, and web gates only on the subagent's fields. An older server rejects the command and the existing "Couldn't Stop Subagent" alert shows.
• New wire fields decode as optional with nil defaults (promptCacheTtlMs, workspaceId, PR permissions, host actions, subagent runId/nativeTaskRef), so older servers behave as before.
• Bluetooth mics are preferred by default: recording now enables Bluetooth HFP so headsets can be listed. A connected headset wins unless the user reorders, matching mobile's default order. The order is stored on the device.
• Setup-queue check reads the thread shell's status, which mirrors the run's state during a live run.
• Branch name: swift/parity-2026-10-11.

Follow-ups (issues are disabled on this repo, so they are tracked here)

1. Against a real server, check Claude-native subagent Stop, Antigravity limit grouping, and workspace-split accounts.
2. On a device, check that AirPods and CarPlay mics appear in Settings → Microphone.
3. Web search rows show the matched PR number as a colored #n label; iOS rows only show PR status.
4. If the server adds a capability flag for subagent.stop, gate Stop on it.
