Original Pull Request: https://github.com/anomalyco/opencode/pull/12185

State: open
Merged: No

This PR prevents the Snapshot.track() flow from adding (untracked) big files into the snapshot system (git).

It changes the code to first do git add -N . which stage the files without content.
Next it iterates over the staged files to find any files larger then defined threshold (1 gig). unstages them AND adds them to $gitdir/info/exclude to prevent them from getting staged again.
Finally it calls git add -- $stagedFiles to stage the files content as well.

To handle existing bloated snapshot dirs, the cleanup method was updated to detect if any existing object blob is bigger then threshold -> nukes the whole snapshot dir.
Leaving the big files causes the git gc --prune process to blow up on memory and hog the system.

Additionally, this PR cleans up the Snapshot code a bit.

Don't be scared from the lines added, I've added tests too 😆

Fixes #6845
