fix(mobile): read display scale and width from the view's scene, not UIScreen.main#12050
Stacked on #12049. iOS 27 makes iPhone apps resizable and SDK 58 stops reading UIScreen.main across Expo. Our terminal, review diff, and composer views still did, for hairline widths, Metal content scale, and the fallback chip width.
They now take the display scale from the view's trait collection and the fallback width from the window they sit in, so hairlines and chip truncation stay right when the app is not full screen or is on another display.
Validation: the full stack compiles on Xcode 27 (Debug simulator build). No behavior change on a full-screen phone.
Model: Claude Fable 5. Harness: Claude Code.
Review fix: chip labels rendered before initial measurement are rebuilt on the first non-zero composer layout; an unmeasured width no longer permanently truncates them. The initial image retains a finite width cap while awaiting measurement, so long labels cannot allocate unbounded images. Swift parsing passes.
Landing preparation: GPT-6.1 Sol in the Codex harness.

Approvability
Verdict: Approved at 240417a
Macroscope's review found this PR approvable — This is a focused iOS scene-geometry bug fix that updates existing rendering and layout paths without adding capabilities, changing defaults, or suppressing static-analysis diagnostics. Full-screen behavior remains unchanged while resizable and external-display scenarios receive view-local sizing and scale handling.

Composer chip sizing now uses view-specific width sources and defers measurement when no positive width is available. Review row hairlines and terminal content scaling use the view’s trait collection display scale.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not treat an unmeasured width as a valid chip width.
If setControlledDocumentJson runs before the view enters a window, both textView.window?.bounds.width and bounds.width can be zero. maximumLabelWidth then falls back to only chipFontSize * 3, so long chips are truncated during makeAttributedDocument. Later layout does not rebuild the attributed document. Treat zero as “not measured” and rebuild after the text container receives a non-zero width.

🟠 High ios/T3ComposerEditorView.swift:984
A controlled document applied before layout can render an unbounded chip image and terminate the app. When no width is available, maximumLabelWidth becomes CGFloat.greatestFiniteMagnitude, so an arbitrarily long token label is measured at full width and passed to UIGraphicsImageRenderer before layoutSubviews can rebuild it; keep a finite fallback cap (such as UIScreen.main.bounds.width) instead.
