Very slow session due to 98GB of git snapshots #3182
Description
I'm using opencode with sonnet 4.5 (aws bedrock) to make some relatively small changes to a Go program. I've sent it two prompts: one to create an AGENTS.md with guidance for future sessions, and a second to make two smallish changes to the main.go. The process has now been running for 2.5 hours. I looked at my AWS cloudwatch logs for Bedrock and I can see that there are 5-8 minutes between API requests. Then I remembered that I forgot to put a opencode.jsonc in this directory to disable git snapshots (yes, this has happened before). This isn't a particular big repo but it does download a lot of deps (about 1GB) for the go build. Seems like opencode's git snapshotting algorithm isn't very smart about avoiding generated binary files.
Adding an opencode.jsonc to deactivate git snapshots, removing the snapshot data, and restarting the session and the task completed in less than 60 seconds. So something is pessimal with how github snapshots are being handled.

@kanaka we are going to do some major optimizations around this soon, sorry about that

Do you know when these optimizations around this are going to happen? I am likely going to have to stop using opencode because it just keeps spawning git commands and consuming disk space in my repo. I tried disabling snapshot with this in my config:
I put this in a file at the root of the repo and at my ~/.config/opencode/opencode.json, but it still just keeps spawning git. I can't even use my computer with opencode running.

Snapshots are filling my hard drive to 0% free space. Please add a free space check to the optimizations

I found out that you have to disable snapshots in the config, then you have to delete the snapshots folder cache that opencode has, or it just keeps doing the bad thing.
