Every LLM-backed feature (Post-Processing, Proofreading, Title
Generation, Property Filler) now reads from one CHAT_PROVIDERS
registry instead of 5 hand-duplicated provider lists, so they always
offer the exact same providers in the exact same order.
- Add Groq as a 5th chat-completion provider (was transcription-only
despite its OpenAI-compatible API and an already-collected key).
- Provider dropdowns disable options with no API key configured
(shown as e.g. "Anthropic (no API key)") instead of silently
failing at runtime when picked.
- Collapse 3 byte-for-byte duplicated resolveProvider() methods
(Proofreader, TitleGenerator, PropertyFiller) plus AudioHandler's
getPostProcessingApiKey() into one resolveChatProvider() helper
(src/ProviderResolver.ts).
- Fix Custom provider: previously Proofreading/Title/Property silently
reused Post-Processing's postProcessingUrl with no visible field to
set it. Renamed to a shared customApiUrl field with its own UI
(createCustomProviderFields), now exposed on every tab that offers
Custom, plus rows on the API Keys tab. Migrates old data.json values
automatically.
- Update README settings reference and getting-started sections to
match.
No behavior change for existing single-provider setups; migration
handles the postProcessingUrl -> customApiUrl rename transparently.
