Subject: [PATCH] feat: add escrow to AcceptsScheme enum
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Look, here's the deal — the x402r escrow scheme has been out there
in the wild, 36 endpoints running on it, and we can't even index them.
That's not hyperbole, folks.

Changes:
- Add 'escrow' to Prisma AcceptsScheme enum
- Update Zod validation to accept 'escrow'
- Update normalization schema (z3.literal → z3.enum)
- Fix type cast in resources.ts
- Add database migration

Closes #663
