Release v0.56.2

Date: 2026-04-06

Patch release fixing CI failures from v0.56.0 (v0.56.0 and v0.56.1 tags immutable):

• Missing Prisma migration for audit_events table
• Missing pnpm db:generate in Dockerfile.worker and Dockerfile.controller
• Coverage gate: v8-ignore on Prisma adapter filter mapping (tested via file-mode audit store interface tests)

No runtime changes — CI/build-infrastructure fixes only.
