feat: standardize tree-sitter test implementations (#2960)

* refactor: standardize C# Tree-Sitter parser tests

This commit standardizes the C# Tree-Sitter parser tests to ensure:
- Variable/function names in sample code match the tests
- Each test only verifies specific identifiers relevant to that test
- Test names clearly indicate what they're testing
- No skipped tests remain
- Only one test exists per structure or combination of structures
- All debug output uses debugLog from helpers.ts

The standardization improves maintainability and clarity while preserving
all existing functionality.

* refactor: standardize C Tree-Sitter parser tests

This commit standardizes the C Tree-Sitter parser tests to ensure:
- Variable/function names in sample code match the tests (using snake_case)
- Each test only verifies specific identifiers relevant to that test
- Test names clearly indicate what they're testing
- No skipped tests remain - tests for unsupported features are removed
- Only one test exists per structure or combination of structures
- All debug output uses debugLog from helpers.ts

The standardization improves maintainability and clarity while preserving
all existing functionality. Documentation has been added for C language
constructs that are not currently supported by the parser.

* feat: dynamically include all tree-sitter WASM files in build process

- Modified esbuild.js to dynamically read and copy all WASM files from tree-sitter-wasms package
- Added error handling and logging for better debugging
- Ensures all language parsers are automatically included without requiring manual updates

* refactor: move test mocks and fixtures to shared locations

Move test mocks to helpers.ts to be shared between test files
Create fixtures directory for shared test data
Move sample TSX content to fixtures/sample-tsx.ts
Update test files to use shared mocks and fixtures

* refactor: simplify tree-sitter debug output

- Remove detailed node inspection to reduce noise
- Keep only essential tree structure output
- Remove duplicate content logging

* refactor: standardize C# tree-sitter test structure

Move C# sample code to dedicated fixture file and create inspectCSharp test
following the same pattern as other language tests. This improves test
organization and maintainability by:

- Extracting sample C# code to fixtures/sample-c-sharp.ts
- Adding inspectCSharp.test.ts for tree structure inspection
- Updating parseSourceCodeDefinitions.c-sharp.test.ts to use fixture

* feat: add language-specific capture processing

- Add language parameter to processCaptures for language-specific handling
- Implement selective HTML filtering for jsx/tsx files
- Update all call sites to pass correct language parameter
- Fix type safety by properly passing language strings

Signed-off-by: Eric Wheeler <[email protected]>

* refactor: move tree-sitter test samples to fixtures

Move sample code from parseSourceCodeDefinitions test files into dedicated
fixtures directory for better organization and reuse:

- Created fixtures directory for language samples
- Moved sample code for C#, C, JSON, Kotlin, PHP, Ruby, Rust, and Swift
- Created inspect test files for each language
- Updated original test files to import from fixtures
- Standardized test options across languages
- No behavior changes, all tests passing

* refactor: standardize tree-sitter test code across languages

Standardize test code structure and naming across all language parsers:
- Rename identifiers to clearly indicate test purpose
- Ensure each code section has descriptive comments
- Group related code sections together
- Maintain language-specific naming conventions
- Keep test structure consistent across languages
- Remove tests for unsupported features

Changes made to:
- C, JSON, Kotlin, PHP, Ruby, Rust, and Swift test files
- Sample code fixtures
- Parser definition tests
- Inspect structure tests

No functional changes - all tests passing with improved maintainability.

* refactor: standardize tree-sitter parser tests across all languages

- Ensure all test structures span at least 4 lines for better parsing
- Create exactly one consolidated test per data structure type
- Use descriptive names that clearly indicate test purpose
- Improve query pattern organization and documentation
- Simplify inspect test files to focus on structure validation
- Implement result caching in test files for better performance
- Remove duplicate and skipped tests
- Follow consistent naming conventions across all languages

* refactor: establish single source of truth for MIN_COMPONENT_LINES

- Move minComponentLines parameter to a file-level constant
- Remove parameter passing to processCaptures function
- Update all references to use the global constant
- Remove redundant local constant declaration in parseFile

Signed-off-by: Eric Wheeler <[email protected]>

* refactor: improve MIN_COMPONENT_LINES implementation

- Changed MIN_COMPONENT_LINES constant to use getter/setter functions
- Updated references to use getMinComponentLines() function
- Modified test helper to set value to 0 during tests
- This establishes a single source of truth while making testing easier

* feat: standardize tree-sitter test implementations

Standardized tree-sitter test implementations across all supported languages:
- Removed debugLog calls from test files
- Implemented consistent line number pattern matching
- Ensured proper test structure and execution order
- Added comprehensive test coverage for supported structures
- Maintained 1:1 mapping between queries, tests and samples
- Documented unsupported features in TODO sections

Signed-off-by: Eric Wheeler <[email protected]>

* docs: document tree-sitter parseable but unsupported structures

Added TODO sections in test files documenting structures that can be parsed
by tree-sitter but currently lack query pattern support:

- Python: f-strings, complex type annotations, pattern matching
- C++: virtual methods, field initializers, base class clauses
- Java: import declarations, field declarations with modifiers
- TSX: React hooks, context providers, event handlers

Added examples and clarifying comments to existing TODO sections.
Enhanced Java query patterns for better structure capture including
lambda expressions, field declarations, and type parameters.

* fix: use correct distDir variable for WASM file copying

The copyWasmFiles plugin was using an undefined targetDir variable when copying
tree-sitter WASM files. Changed to use the correctly defined distDir variable,
fixing the build process.

* lint: remove unused imports and variables from tree-sitter tests

Removed unused imports and variables from tree-sitter test files to fix linting errors:
- Removed unused goQuery import from helpers.ts
- Removed unused imports and mockedFs variables from language-specific test files
- Cleaned up test files to only import what they use

+   (with_clause (with_item) (with_item) (with_item))
+   Example: with (open('file1.txt') as f1, open('file2.txt') as f2)

-class Rectangle(Shape):

+   (case_pattern (as_pattern (case_pattern (class_pattern)) (identifier)))
+   Example: case {"name": str() as name, "age": int() as age}

+5. Nested Function Definitions with Scope Modifiers:
+   (function_definition (block (function_definition (block (nonlocal_statement) (global_statement)))))
+   Example: Nested functions with nonlocal/global declarations
