Error while trying to read files

[tracy-codes]

After upgrading to the latest release of Devon, when it attempts to read a file that does exist in the current working directory, it looks like it is unable to actually read the file or there's some hiccup in the subprocess system. It seems like it can open the first file, but then when it attempts to open the second file, that's where it struggles

In this example, I have a rust monorepo where the directory structure it's attempting to access is like <root_workspace_dir>/<crate>/tests/stress_test.rs which it can read. When it attempts to read the second file, located at a path like <root_worksapce_dir>/<crate>/src/net.rs it can't read the file.

System specs:

• Device: 2023 16" Macbook Pro w/ M3 Max CPU
• devon_agent version: 0.1.25
