* feat(podcasts): integrate model registry for profiles and credential passthrough
Replace loose provider/model string fields with record<model> references
in podcast profiles, enabling credential passthrough to podcast-creator.
Backend:
- EpisodeProfile: outline_llm, transcript_llm (record<model>) replace
outline_provider/outline_model strings. New language field (BCP 47).
- SpeakerProfile: voice_model (record<model>) replaces tts_provider/
tts_model strings. Per-speaker voice_model override support.
- Migration 14: schema changes making legacy fields optional, adding new
record<model> fields.
- Data migration (migration.py): auto-converts legacy profiles to model
registry references on startup. Idempotent.
- podcast_commands.py: resolves credentials for ALL profiles before
calling podcast-creator.
- New /api/languages endpoint (pycountry + babel) with BCP 47 locale
codes (pt-BR, en-US, etc.).
Frontend:
- Episode/speaker profile forms use ModelSelector instead of manual
provider/model dropdowns.
- Language dropdown with BCP 47 codes in episode profile form.
- Per-speaker TTS voice model override in speaker profile form.
- "Templates" tab renamed to "Profiles".
- Setup required badge on unconfigured profiles.
- i18n updated across all 8 locales.
Closes#486, closes#552
* fix(i18n): remove unused legacy podcast provider/model keys
Remove 10 orphaned i18n keys across all 8 locales that were left behind
after replacing manual provider/model dropdowns with ModelSelector.
* fix: address review violations in podcast model registry
- P1: Remove profiles with failed model resolution from dicts to prevent
podcast-creator validation errors on unrelated profiles
- P2: Use centralized QUERY_KEYS.languages instead of inline key
- P3: Fix ISO 639-1 → BCP 47 in model field description and CLAUDE.md
- P3: Update "templates" → "profiles" in locale string values (all 8)
* chore: bump version to 1.8.0
* docs: update CLAUDE.md and user docs for error handling and podcast retry
Add missing documentation for features introduced in v1.7.2 (#590) and
