security: harden BOM processing and LaunchAgents detection

Browse Source 
- Add path traversal protection in BOM receipt parsing
- Remove invalid ~/Library/LaunchDaemons path references
- Strengthen LaunchAgents matching (min 5 chars, exclude com.apple.*)
- Add 300s timeout to brew cask uninstall to prevent hangs
Addresses security review findings from V1.21.0 audit.
