v0.0.29: Russian locale, resilient world creation, and responsive UI

[ackness]

Summary / 摘要

Prepare the complete v0.0.29 release:

• add first-class Russian (ru-RU) Web and desktop localization, a catalog-driven Web locale registry, script-safe locale resolution, locale scaffolding/validation, and localized plugin/world/prompt handling
• prevent AI world creation from rejecting ordinary lore vocabulary, and repair explicit WORLD.md meta wording without regenerating an otherwise valid package
• improve responsive, accessible, and theme-aware behavior across landing, world selection/editing, session preparation, gameplay, settings, and debugger surfaces
• notify packaged desktop players when a newer stable Covel release is available
• bump all 46 workspace manifests and release documentation to 0.0.29

The core UI catalog extension point is intentionally build-time: runtime community plugins can localize their own content, but cannot execute in the browser/Electron main process or replace bundled core UI catalogs.

Related issue / context / 关联

• Implements the fix reported in [Bug] World generation: lore quality check false-positives on common English words (framework/model/cost/api) #50; the issue will be closed after the v0.0.29 Release is published.
• Implements Russian support and the source-distributed locale extension path requested in [Feature] First-class Locale Registry: add Russian (ru-RU) without editing framework files #51; the issue will be closed after the v0.0.29 Release is published.
• Supersedes fix(create): avoid false positives for natural lore vocabulary #52 with the maintainer implementation in commits 969f5252 and 7a815438, which adds narrower contextual detection plus targeted lore-only repair and broader regression coverage.
