Add ClearanceKit to security apps

[craigjbass]

Proposed Changes

ClearanceKit — File-access control for macOS that protects sensitive user data (SSH keys, credentials, messages, browser cookies) from supply-chain attacks. Intercepts file-system operations via Endpoint Security and enforces code-signing-based policies, so a trojanised npm package or compromised build tool is denied access even if it runs under your user account.

Key features:

• Policies bind to cryptographic signing identities rather than file hashes, surviving software updates indefinitely
• Maintains a live in-memory process tree with cached ancestor chains, enabling ancestry-aware policy rules
• Ships with built-in presets for common apps (Signal, Notes, Contacts, Discord)
• GUI for real-time denied access visibility and one-click allow rule creation
• Supports MDM-managed policy delivery for enterprise deployment
