add autoblog support

[ralyodio]

two providers so far:

https://outrank.so and https://crawlproof.com -- via webhooks + secret

I can take a focused first slice here: add an autoblog adapter category with Outrank and CrawlProof webhook-backed providers, keeping configuration secret-key based and tests dry-run only so no live webhook calls or secrets are needed.

Submitted the focused implementation here: #212

Summary:

• adds an autoblog provider contract and contract tests
• adds Outrank and CrawlProof webhook-backed providers using vault-stored URLs and optional HMAC signing secrets
• registers the new autoblog category in the CLI adapter registry
