--readonly has no effect

[MikkelSchubert]

Running agent-vm with the --readonly option has no effect, seemingly because fuse does not support remounting the project folder:

$ agent-vm --readonly shell
Mounting project directory as read-only...
fuse: unknown option(s): `-o relatime,user_id=1001,group_id=1001,remount'
  Resources: CPUs: 2, Memory: 4 GiB, Disk: 10 GiB
VM: agent-vm-dir-72262632 | Dir: /home/username/dir
Type 'exit' to leave (VM keeps running). Use 'agent-vm stop' to stop it.
vm:dir% touch foo
vm:dir% ls foo
foo

Moreover,

• it makes no difference is if the VM is started or stopped when you run the above command
• the --git-ro option does work and attempting to touch a file in .git fails.

Versions:

• agent-vm c490c0a
• limactl v2.0.3
• qemu v8.2.2
• Linux Mint 22.3
