feat: display numeric constraints for parameters

Add formatNumericConstraints function to display minimum, maximum,
exclusiveMinimum, and exclusiveMaximum constraints for path and query
parameters in the documentation.

- Add constraint formatting with proper mathematical symbols (, , >, <)
- Support range notation for combined constraints [min, max], (min, max)
- Display constraints in parameter description area
- Add comprehensive unit tests for all constraint types
- Work in both documentation view and Try it out mode
