fix: correct commit hash typo in audit README

[consumeobeydie]

What changed? Why?

In audits/README.md, the commit hash displayed for the TEE Multiproof Contracts 2 audit (04/10/26) was incorrect.

Before:
fe2af8cbffefa44bbb1a3917507f8bd8ebec7a2 (39 characters — missing leading f, returns 404)

After:
ffe2af8cbffefa44bbb1a3917507f8bd8ebec7a2 (40 characters — correct SHA, returns 200)

The URL in the same row was already correct. Only the display text was wrong.

Notes to reviewers

Single character fix — the display text and the link URL pointed to different commits. The correct hash ffe2af8cbffefa44bbb1a3917507f8bd8ebec7a2 matches the adjacent row (AggregateVerifier Multiproof Contracts 2) which was audited at the same time.

How has it been tested?

Verified both hashes:

• ffe2af8cbffefa44bbb1a3917507f8bd8ebec7a2 → HTTP 200 ✅
• fe2af8cbffefa44bbb1a3917507f8bd8ebec7a2 → HTTP 404 ❌
