Release v0.56.3

Date: 2026-04-06

Patch release fixing CI failures from v0.56.0 (v0.56.0–v0.56.2 tags immutable):

• Missing Prisma migration for audit_events table
• Missing pnpm db:generate in Dockerfile.worker and Dockerfile.controller
• Coverage gate: exclude src/storage/sqlserver/** from default coverage (has dedicated test-sqlserver CI job); v8-ignore Prisma adapter filter mapping tested via file-mode audit store

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