frostx 0.1.0

frostx monitors project directories for inactivity. Once a configured inactivity threshold elapses (e.g. "90 days since any file was modified"), frostx executes a pipeline of **actions** - e.g., checking git state, creating archives, uploading backups, deleting local copies. Automating the lifecycle of projects, frostx helps users manage disk space and maintain a clean workspace.
