docs: Update pretooluse documentation with additional parameters and constraints

- Added parameters for operation, filePath, line, and character to enhance clarity.
- Clarified the library ID format in the MCP context section.
- Introduced a constraint on the maximum number of calls per question for better performance.

These updates improve the comprehensibility and usability of the pretooluse documentation.
