feat: add finch-daemon

[pendo324]

Issue #, if available:

Description of changes

Adds finch-daemon, so that it starts inside the VM and is exposed to processes inside the VM (via /run/finch.sock and /var/run/docker.sock), and processes on the native macOS host (via /path/to/lima/data/finch/sock/finch.sock).

To make this possible, these changes had to be made:

1. Added finch-daemon specific logic to ./finch.yaml.d/mac.yaml
   1. This logic makes it so that the finch-daemon binary and service file are copied into the VM, and then starts the daemon using systemd
2. In Makefile.darwin, changed the order so that the finch-daemon specific provisioning script would be the final script, after being merged
   1. Also added a add-daemon-mount target, which makes it so that duplicate mounts are not added to Lima. This is done to avoid the default lima provisioning scripts failing due to trying to mount/unmount a directory twice (the end result is users may see cloud-final.service fail after shelling into the VM. although this should only ever really impact developers, it was easy enough to fix)
3. Added [email protected]

This change also currently relies on a fork of finch-core, which actually has the code necessary for building finch-daemon. Once runfinch/finch-core#424 is merged, I'll update this PR to remove the use of a different finch-core upstream.

Testing done

• finch-daemon works as expected on macOS:

Turns out git.exe isn't in the Windows runner's PATH. Added it here: runfinch/infrastructure#769

After that gets deployed to the runners, it should resolve the Windows build failures we're seeing.
