Add a guarded "Sign & notarize macOS app" step to build.yml that signs
dist/DataTools.app with the Developer ID (hardened runtime + entitlements
+ secure timestamp), notarizes via notarytool, and staples the ticket —
running before DMG packaging. The step exits 0 with a warning when the
MACOS_* secrets are absent, so dry-run dispatches still produce an
(unsigned) build.
Add build/macos/entitlements.plist with the hardened-runtime entitlements
a frozen PyInstaller/CPython app needs (JIT memory, library-validation
disabled for bundled .so/.dylib + Tesseract). Update build/README.md to
reflect that macOS signing is now wired and only needs the secrets.
