Summary by CodeRabbit

• Updated Signing
  • App signing now uses a new signing engine and supports both certificate-based and ad hoc signing.
  • Entitlement data is passed through during signing, including data supplied from entitlement files.
• Validation
  • Signing rejects invalid app or entitlement file paths and duplicate entitlement paths.
• Compatibility
  • Signing setup no longer requires selecting a signer when creating a signing context.

📝 Walkthrough

The change replaces the zsign integration with RCodesign, adds a dependency-injected signer interface, and updates signing and executable-analysis call sites to use it.

Changes: Signer backend migration

Layer / File(s)	Summary
Signer interface and context Sources/XKit/Signer/Signer.swift, Sources/XKit/Signer/SignerImpl.swift, Sources/XKit/Signer/SigningContext.swift	A signer protocol, identity type, and dependency value replace signer discovery through SigningContext. The previous Signer implementation is removed.
RCodesign implementation Package.swift, Sources/XKit/Signer/RCodesignSigner.swift	The package replaces zsign with swift-rcodesign. RCodesignSigner validates signing paths, maps identities and entitlements, and delegates signing and executable analysis to RCodesign.
Signing and analysis call sites Sources/XKit/DeveloperServices/App IDs/DeveloperServicesAddAppOperation.swift, Sources/XKit/Signer/AutoSigner.swift, Sources/XToolSupport/DevCommand.swift, Sources/XKit/Integration/IntegratedInstaller.swift	Call sites use the injected signer. AutoSigner encodes entitlement data as XML property-list data and passes shallow: false. SigningContext initialization no longer throws.
