* feat(ios): add Russian locale
Add Russian translations to Localizable.xcstrings for all 591 catalog
entries (reusing matching Android translations and translating the rest);
zh-Hans and format placeholders are preserved.
* fix(ios): make Russian selectable and use correct plural forms
- add AppLanguage.russian ("ru"), its display name, the AppleLanguages
override, and register ru in the Xcode project's knownRegions so the
language picker can actually select Russian
- add Russian one/few/many/other plural variations for %lld sessions,
%lld attachments and %@, %lld sessions
- use count-agnostic phrasing for the other dynamic counts (tools, edits,
lines, chars, findings, notes, queued messages, questions, ...)
- correct Input/Output to Ввод/Вывод
- cover the new language case in ThemePrefsTests
* fix(ios): use Russian plural forms for the remaining count labels
* fix(ios): pass the step count to the plural localization
* fix(ios): pass tool counts to the plural localization
* fix(ios): keep the singular English tool-group labels

Move tool output into a live sheet with group navigation and full-content copying. Keep lightweight grouped summaries inline, add agent process pages, and preserve transcript reading position.\n\nAdd real transcript and sheet regression coverage with localized summaries.
Use unified 16pt Dynamic Type body text, clearer Markdown spacing, and a shared reading column. Preserve transcript anchors across typography changes and bound tool command previews to two lines. Add layout and typography regression tests.
Add viewport-driven paging with layout acknowledgements, bounded retries, cancellation gates, and epoch-safe history retention.
Preserve transcript anchors and expansion state, fix tool-group identity collisions, and serialize Android history coordination on Main.
Reduce per-scroll composition and layout work; add native regression tests, CI coverage, and profiling guidance.
