support float types (#77)

[alexgarzao]

Closes #77

This PR adds support for float types (float32 and float64) to the validation framework, ensuring that all relevant validation operations can be performed on float fields alongside existing types. The changes cover analyzer logic, code generation, test coverage, and helper functions to fully integrate float handling.

Validation logic and analyzer updates:

• Added <FLOAT> as a valid type for all relevant operations (e.g., eq, required, gt, gte, lt, lte, min, neq, in, nin) in internal/analyzer/operations.go, enabling validation rules for float fields. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Code generation enhancements:

• Updated internal/codegenerator/condition_table.go to generate correct Go validation code for float fields across all supported operations, including error messages and logical operators for set operations. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Test coverage improvements:

• Expanded unit tests in internal/analyzer/operations_test.go to verify float support for all operations, and added new tests in internal/codegenerator/get_test_elements_numeric_test.go specifically for float fields. [1] [2] [3] [4] [5] [6] [7]
• Added code generation tests for float fields in internal/codegenerator/build_validator_test.go.

Helper function updates:

• Modified internal/common/helpers.go to map normalized float types to their Go equivalents for basic, map, slice, and array forms. [1] [2] [3] [4]

Miscellaneous:

• Updated the Makefile to handle float-based generated test files for end-to-end testing.
• Renamed a test function for clarity in get_test_elements_numeric_test.go.

Pull Request Overview

This PR adds comprehensive support for float types (float32 and float64) to the ValidGen validation framework, extending the tool's capabilities to handle floating-point number validation alongside existing string, boolean, and integer types.

Key Changes

• Added <FLOAT> type support to all relevant validation operations in analyzer and code generation components
• Implemented complete test coverage for float validation scenarios including unit, integration, and end-to-end tests
• Restructured numeric test organization by separating integer and float tests into distinct files and functions
