Subject: Fix read-file from exploding with path not found error.

- There were a few hiccups here. Somehow 2.5-flash wasn't actually abiding by our tool schema. Instead it was inferring `path`. To semi-combat this I've renamed `file_path` -> `path`.
- We weren't elevating errors that were created via schema validation. Instead both the `glob` and `read-file.ts` now surface this.
- In error scenarios (like failing schema) we were improperly surfacing these as success cases because we were overriding tool status.
