fix: Push tool calls to absolute paths (#1055) (#1057)

Make several changes to guide the model to request absolute paths,
reducing frequent accidental relative path tool call failures.

- Switch the parameter name: path --> absolute_path.
- Update the tool definition to strongly require an absolute path.
- Update the system prompt to indicate absolute paths are required.
- Update the system prompt tool use examples to use absolute paths.

Test case:

Open GC in GC: "Locate the primary file calling genai"
- Expected: Model opens files with absolute path, successfully.
- Actual (pre-patch): Failure, attempts to read with relative path.
- Actual (post-patch): Success, attempts to read with absolute path.
