Fix: Pre-upgrade Backup Fails on Skill Directories
Bug
gentle-ai upgrade failed with "backup source path is a directory" when the user had custom skill folders (e.g., .gemini/antigravity/skills/add-educational-comments/). The backup system expected only file paths but received directory paths, causing the entire upgrade to abort.
Fix
Directories in the backup path list are now silently skipped instead of causing a fatal error. They are recorded in the manifest as not-backed-up (same pattern as non-existent files). Only individual files are actually copied to the snapshot.
Upgrade
