major code restructuring

[SadriShehu]

This pull request refactors schema generation and testing in the Go codebase, with a focus on improving error handling, simplifying schema construction, and expanding test coverage for edge cases and recursive structures. The main logic for generating schemas is made more reusable, and tests are enhanced to ensure more robust and accurate schema generation.

Schema generation improvements:

• Refactored the construction of the genSchema map in main.go to use the new schematic.GenerateSchema function, simplifying schema definition and reducing redundancy.
• Improved error handling in schematic.BuildEvents by replacing log.Fatalf calls with error returns using fmt.Errorf, making the function more suitable for use as a library and easier to test. [1] [2]

Testing enhancements:

• Replaced the old TestGenerateProperties with several new, focused tests in schematic/generator_test.go to cover edge cases (such as maps, interfaces, time fields, byte slices, skipped fields, and unsigned integers), recursive structs, snake_case conversion, and required fields logic. This greatly increases test coverage and robustness of the schema generator. [1] [2]
• Cleaned up imports in the test file by removing unused packages and adding only the necessary ones.

Other changes:

• Removed the now-obsolete schematic/schema.json file, as schema validation is now handled dynamically in tests rather than with a static file.
