feat(checks): unify inspection scope in checks/scope.ts

Single source of truth for what pygienium inspects (implementation-code
extensions, exclude dirs, .d.ts/.min.* exclusions) shared by recon,
dead-code, deep-modules, defensive-guards, comments, and complexity.
Every scan task and agent prompt injects the shared scope rules instead
of copy-pasted per-check lists.
