Update webhook docs on SDK

[sauravpanda]

Summary by cubic

Updated the webhook guide to document the new HMAC signature scheme with timestamp and canonical JSON, and to switch payload fields to snake_case. Clarifies agent.task.status_update statuses and adds Python/TypeScript verification examples.

• Migration
  • Verify using X-Browser-Use-Signature and X-Browser-Use-Timestamp; compute HMAC over "{timestamp}.{sorted-keys JSON}" and reject requests older than 5 minutes.
  • Expect task_id, session_id, and optional metadata instead of taskId/sessionId.

^{Written for commit 3486667. Summary will update on new commits.}
