Greptile Summary

This PR adds programmatic webhook management via Server SDKs, introducing an announcement blog post, a changelog entry, and substantially expanded webhook documentation. The docs page now covers console setup, CRUD + secret-rotation SDK samples across all supported languages, a verification section with timing-safe HMAC comparisons, and updated screenshots. Prior concerns raised in review threads (timing-safe comparisons, Swift XOR operator, tablesdb event examples) appear resolved in this revision.

Confidence Score: 5/5

Safe to merge; only a minor P2 style inconsistency between docs and blog Rust snippets remains.

All substantive concerns from prior review threads have been addressed. The single remaining finding is a cosmetic inconsistency in the enabled parameter value between two Rust code examples and does not affect correctness or user safety.

No files require special attention.
