This will allow for several things 1. Automatic sync, not driven by shell usa…ge 2. Keep database writes out of the hot path, which becomes an issue with certain filesystems 3. Allows us more flexibility 4. Potential for fully realtime sync The downsides are that this is significantly more complexity. I've intentionally not included an automatic daemon start/stop here, and kept it opt-in. It will likely remain that way for a while. ## Checks - [ ] I am happy for maintainers to push small adjustments to this PR, to speed up the review cycle - [ ] I have checked that there are no existing pull requests for the same thing

I’ll merge soon it as it seems usable, but it will still need a bunch more testing as I’m sure there are cases where it doesn’t work so well

If anyone fancies trying it, add

[daemon]
enabled = true
socket_path = "/some/path/to/where/you/want/the/unix/socket"

and run atuin daemon somewhere

It will

Bind the unix socket, and start a grpc service
Maintain a map of “in progress” commands in memory, rather than in sqlite
Stop writing to the database while you’re using the terminal
Run a regularly scheduled background sync, by default every 5m but configurable with daemon.sync_frequency, in seconds
