Vouch Request: alihani714 (Hardened Webhook Schema)

[alihani714]

Hi team! I'm reaching out to be vouched for so I can contribute to Trigger.dev.

I've already prepared a high-quality fix for the Webhook Schema validation in PR #3354 (which was auto-closed as unvouched). My implementation includes:

• Strict ID prefix validation for run_, task_, org_, etc.
• Dashboard URL sanitization logic.
• Git metadata consistency checks to prevent malformed injections.

I'm excited to help improve the security and reliability of the platform. Could you please vouch for me so I can reopen the PR? Thanks!
