Webhooks reference page + docs payload fix

New feature · Improvement.

A dedicated Webhooks reference now documents the full delivery contract: event catalog, exact payload, signature verification with a complete receiver example, retry policy (3 attempts, exponential backoff, 10 s per-attempt timeout, no long redelivery queue — backfill via GET /messages), duplicate and ordering semantics, and a troubleshooting checklist.

Docs fix: the webhook example previously showed message.timestamp as an ISO string — deliveries actually carry epoch milliseconds (a number). The payload itself is unchanged; only the documentation was wrong.

Machine-readable docs surface: llms-full.txt + CORS-open spec

Improvement.

The complete documentation is now published as a single markdown file at https://developers.wasync.app/llms-full.txt for LLM ingestion, alongside the existing https://developers.wasync.app/llms.txt index.

/openapi.json, /llms.txt and /llms-full.txt are now served with Access-Control-Allow-Origin: *, so browser-based spec viewers, SDK generators and AI agents can fetch them cross-origin. This changelog is also new.
