Grep/Glob require ripgrep but it isn't declared or checked

[Scratchydisk]

GlobTool (glob.py:9) and GrepTool shell out to rg:

command = ["rg", "--files", directory, "--glob", pattern]

ripgrep isn't a declared dependency and there's no existence check. When it's missing, the tools fail with a raw FileNotFoundError: [Errno 2] No such file or directory: 'rg'. In an agent loop this is opaque: the model can't search, reads nothing, and returns no/garbage citations with no indication that the cause is a missing binary.

Suggested fix: detect rg at startup and emit a clear, actionable error (or document it as a hard requirement / fall back to a Python search).

Also I noticed that rg path is hardcoded and not dynamically resolved. For me on mac with rg via homebrew this needed manual adjustment of the path.

But honestly this project is really great even for us gpu poor!
