Add Smallest AI (Pulse) to the leaderboard

[harshitajain165]

Closes #4

What this adds

Provider: Smallest AI — https://smallest.ai
Model: Pulse

Implementation details

• src/lib/providers/smallest.ts — transcription via POST https://api.smallest.ai/waves/v1/stt?model=pulse with raw application/octet-stream audio and word_timestamps=true
• src/lib/providers.ts — registered in the PROVIDERS array
• src/lib/transcribe.ts — wired into PROVIDER_MAP
• prisma/seed.ts — added to the seed list
• public/providers/smallest.svg — provider logo
• .env.example — documents SMALLEST_API_KEY

The API is synchronous (no polling needed) — audio bytes in, JSON transcript out — consistent with how the other pre-recorded providers work here.

📝 Walkthrough

Walkthrough

This PR adds Smallest AI Pulse as a new speech-to-text provider to the comparison leaderboard. Configuration includes an API key environment variable, provider metadata with slug and branding, seed data for database setup, and a complete transcription function that authenticates to the Smallest Waves API and parses word-level timestamps from the response.

Changes

Smallest AI Provider Integration

Layer / File(s)	Summary
Provider configuration and metadata .env.example, src/lib/providers.ts, prisma/seed.ts	Environment variable SMALLEST_API_KEY is added for API authentication. Provider entry with slug smallest, logo URL, color, and model is registered in PROVIDERS. Seed script includes Smallest AI for database population.
Provider implementation and dispatch integration src/lib/providers/smallest.ts, src/lib/transcribe.ts	New module transcribeWithSmallest authenticates via API key, POSTs audio as application/octet-stream to Smallest Waves STT endpoint with word_timestamps=true, parses JSON response, maps word objects to internal WordTimestamp format, and returns transcript text, timestamps, and request duration. Function is imported and registered in PROVIDER_MAP for dispatch via transcribeForProvider, and provider name is added to sanitizeError for consistent error messaging.

In `@src/lib/providers/smallest.ts`:
- Around line 40-42: The thrown Error in the response.ok branch of the Smallest
AI request handler doesn't include a retry-parsable status token; update the
throw in the response handling (the if (!response.ok) block) to append a
standardized token containing the numeric HTTP status so isTransientError can
parse it (for example: include `[status:${response.status}]` or a similar
"status:<code>" token in the Error message along with the existing body and
status). Ensure the message still contains the original status and response text
but adds the bracketed status token so retry logic can detect 429/5xx responses.
