Feature request: plain file formatter in daemon mode

There is test.kt: fun main(){print("hello world")}
And im trying to format it:
echo pre-commit test.kt | nc localhost 43649
0
Nothing to format
Why this happens? Tried both relative and absolute paths.
Also, really great project, especially daemon! For envs like neovim there no kt formatter that would format faster then in 1-2 seconds after format request, so you project is just a lifesaver!

Start by reproducing the reported command with test.kt: echo pre-commit test.kt | nc localhost 43649, then trace the daemon's request handling for relative and absolute paths. Done means a plain Kotlin file request is recognized and formatted rather than returning "Nothing to format".
