Reads a file from the local filesystem.

file_path must be an absolute path.
Reads up to 2000 lines by default.
You can optionally specify a line offset and limit (especially handy for long files), but it's recommended to read the whole file by not providing these parameters
Results are returned using cat -n format, with line numbers starting at 1
Reads images (PNG, JPG, …) and presents them visually. Reads PDFs via the pages parameter (e.g. "1-5", max 20 pages/request; required for PDFs over 10 pages). Reads Jupyter notebooks (.ipynb) as cells with outputs.
Reading a directory, a missing file, or an empty file returns an error or system reminder rather than content.
Do NOT re-read a file you just edited to verify — Edit/Write would have errored if the change failed, and the harness tracks file state for you.
