fix(stt): offer every whisper.cpp language in the regenerate picker - #468
Conversation
The "Regenerate as" selector only listed 11 hand-picked languages while the shipped whisper small model transcribes ~100. TRANSCRIPT_LANGUAGE_CODES in schema/index.ts is now the single source of truth (mirrors whisper.cpp's own g_lang table) for both the zod schema and the picker, which sorts by name localized via Intl.DisplayNames (falling back to whisper's English name) instead of a hardcoded list of bare codes.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The picker now exposes the full canonical language list with localized labels, but an unsupported persisted transcript language could still produce a selector value outside that list; the change is mergeable with explicit owner awareness and follow-up validation.

A subagent review caught that the first commit only widened SourceTranscriptModal, which NewEditorShell never mounts (LeftPanel is always rendered with active="chat"). The picker a real user opens is MediaStage.tsx's own, separate <select>, still hardcoded to auto/en/fr/es. - Extract language-label resolution into lib/ai-edition/transcription/languageLabels.ts (languageLabel, sortedLanguageOptions) so both pickers share one implementation instead of drifting the way the original hand-duplicated lists did. - Wire MediaStage.tsx's picker onto it. - Fix the "detected language" pill in both components to show a localized name instead of the raw whisper code. - Guard Intl.Collator the same way Intl.DisplayNames already was, and cache a failed Intl.DisplayNames construction instead of retrying it on every language in the list. - Move TRANSCRIPT_LANGUAGE_NAMES out of the schema module (bundled into the Electron main process) into the new UI-facing module, and collapse three copies of `Exclude<TranscriptLanguageCode, "auto">` into one exported WhisperLanguageCode type.

CodeRabbit review: AxcutTranscript.language is an unvalidated z.string().min(1), so a stored transcript holding a code outside the ~100 known ones would leave the select unmatched and submit a code Whisper can't resolve. Parse it through transcriptLanguageSchema and fall back to "auto" in both the init and the open-sync effect.
