refactor(permission): consume structured bash payload
- require @gotgenes/pi-permission-system >=25.3.0 and read the complete local bash command from PromptPermissionDetails.payload instead of session-walking recovery - remove the @sikongjueluo/pi-permission-shared package - pass the triggering command unit to handlers via HandlerContext.unit in place of details.command - add shadow-only AI judge modules for evidence projection, structured verdict requests, and prompt building, with vitest coverage - record ADR 0004 and mark the ADR 0001 recovery mechanism superseded - exclude pi-permission-system 25.3.0 from the pnpm minimumReleaseAge guard
