[Accessibility]: Viewer global shortcuts should ignore IME composition #912
Description
Problem
The Viewer-wide keyboard shortcut handler does not inspect KeyboardEvent.isComposing. While an IME composition is active, composition confirmation can surface keys such as /, ?, s, e, +, or Escape; the Viewer may open Finder/help, change the preset/theme, export, zoom, or dismiss state instead of leaving the composition to the input method.
Scope
This is distinct from #902, which protects the Finder panel's local Enter/Escape behavior. This issue covers document-level Viewer shortcuts before they dispatch to any feature.
Expected
During IME composition, document-level Viewer shortcuts perform no action and do not prevent the key's default behavior. Ordinary shortcuts retain their existing behavior.
I will add a real-browser regression that dispatches composing shortcut keys and confirms the Viewer state remains unchanged.

I reproduced the missing document-level composition boundary and will submit a focused Viewer fix with browser coverage.
fix: resolve ten workflow, sequence, brand and keyboard issues

Applied and verified outlier27-cell's #913 in our 3.1.0 fork: commit.
Global shortcuts now return before changing Viewer state when isComposing is true or keyCode is 229. Capture-phase chapter/selection handlers and local panels use the same composition boundary, preventing an earlier listener from consuming the key first.
The real-Chrome regression dispatches the shortcut set, including slash, help, theme, preset, export, presentation, Radar, Lens, Route, zoom and chapter controls, and verifies that composition does not prevent default or open panels. Ordinary shortcuts remain covered by the maintained browser suite. Installed-package checks pass; this does not certify a physical IME or Safari.
