feat: add Go test parser support

[kubrickcode]

Add gotesting strategy for parsing Go test files (*_test.go)

• Extract func TestXxx(t *testing.T) format test functions
• Extract t.Run() subtests (flat structure)
• Integrate tree-sitter Go language support

Summary of Changes

Hello @kubrickcode, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the system's capability by adding comprehensive support for parsing Go test files. It introduces a dedicated strategy that leverages tree-sitter to accurately identify and extract both top-level test functions and nested subtests, ensuring that Go projects can be properly analyzed for their testing structures.

Highlights

• Go Test Parser Support: Introduced a new strategy to parse Go test files (*_test.go), enabling the system to understand and extract Go-specific test structures.
• Test Function Extraction: The parser can now correctly identify and extract standard Go test functions following the func TestXxx(t *testing.T) format.
• Subtest Recognition: Implemented logic to extract t.Run() subtests, treating them as a flat structure within their parent test suite.
• Tree-sitter Integration: Integrated tree-sitter's Go language support to provide robust and accurate parsing of Go source code for test detection.

Code Review

This pull request introduces a parser for Go test files, which is a valuable addition. The implementation is well-structured and includes a comprehensive set of tests. My review focuses on a few areas for improvement: enhancing test performance by enabling parallel execution, ensuring associated tests are updated to reflect changes, and refactoring a function to align better with the style guide's preference for pure functions. Overall, this is a solid contribution.

Code Review

This pull request introduces a parser for Go test files, which is a great addition. The implementation uses tree-sitter and correctly identifies test functions and subtests. The code is well-structured and includes a comprehensive test suite.

I've identified a correctness issue in the validation of test function parameters and a potential improvement for handling string literals. I've also suggested an additional test case to cover the parameter validation logic. Overall, this is a solid contribution.

Code Review

This pull request introduces a new parser for Go test files using the go-testing strategy. The implementation leverages tree-sitter to accurately parse *_test.go files, extracting both top-level TestXxx functions and t.Run subtests into a flat structure. The changes also include integrating Go language support into the core tree-sitter parser setup, along with a comprehensive suite of unit tests that cover numerous edge cases and ensure the parser's correctness.

The code is well-structured, adheres to the repository's Go coding conventions, and the refactoring in treesitter.go improves maintainability. I have one suggestion to optimize a loop in the parameter validation logic for better memory efficiency.
