fix(prompt): reduce initial token usage by not sending file tree

Carlos Alexandro Becker created 1 week ago

It can get quite big - the LLM can use the `ls` tool at any time to
build the tree, so I think this is probably a good tradeof, as it would
save a lot of prompt usage, especially on big projects.

Sending a prompt (`hi`) in Crush's root dir, no MCPs/LSPs, qwen coder 3:

17.9k tokens

11.7k tokens
