chore: port patches to nightly 0.1.8-nightly.20261109.4429 - #87

Ports every patch layer to nightly 0.1.8-nightly.20261109.4429 (dc7270581800) and drops patches-ios/0010.

Upstream changes the port follows

• #33131 removed plan mode, contextWindowMeterEnabled and ContextWindowMeter. Shared 0001 keeps only statsForNerdsEnabled. Shared 0003 brings back compactDisabledReason in ChatView.tsx for the stats compact action. iOS 0003 sends /compact with DEFAULT_PROVIDER_INTERACTION_MODE and no longer exports onUpdateInteractionMode.
• #27753 added the turn model and #28047 added Codex prompt suggestions. Shared 0001 adds its fields and test-harness arguments next to them.
• #32287 (shell cache resume) moved the omission key into ShellOriginIdentity. tt 0003 still forces omitIdleSubagents: false there.
• iOS 0004: AppSymbol is split per platform, so checklist goes in AppSymbol.android.tsx. StatusLabel.label is now nullable.
• iOS 0005: the new widget-read account guard required a Clerk token provider. A direct-push transport now counts as signed in too, so the Live Activity still primes without T3 Connect.
• Small context merges in tt 0004 (creationSource next to openedByThreadId, Android alert maps) and tt 0005 (MOBILE_APP_URL).

Dropped

patches-ios/0010 (iOS Mermaid diagrams). Upstream renders Mermaid fences on mobile itself (#32190, d0807b7, in this nightly) and closed #31102. The patch, its check, its fork-changes.md row and its ported-prs.json entry are removed.

Verification

./t3code-customize checks --source <worktree>: all tests, browser tests, typechecks (mobile included) and lint pass on the desktop/server stack and on the full iOS stack. Desktop build, startup and iOS build have not been run yet.
