fix: add proper t.Parallel() and import path handling

## Fix Issue #188: Proper t.Parallel() Generation
- Add t.Parallel() at the top level of test functions when -parallel is used
- Keep t.Parallel() in subtests as well for optimal parallelism
- This satisfies the tparallel linter and Go testing best practices
- Updated both standard and testify templates
- Updated all golden test files to reflect new behavior

## Fix PR #179: Missing Import Paths
- When receiver and methods are in different files, imports from all files
  in the package are now included in the generated test
- Fixes compilation errors when types come from separate files
