fix: trim whitespace from file paths in read/edit/write tools

Some models (e.g., ornith:9b) append trailing newlines to tool call
string arguments. The read tool rejected these with "File not found"
because the path included a \n character. Adding .trim() to filePath
parameters in read, edit, and write tools fixes this for all models.
