Ismo Vuorinen 4f12c4d3dd feat(lint): add many linters, make all the tests run fast! (#23)
* chore(lint): added nlreturn, run linting

* chore(lint): replace some fmt.Sprintf calls

* chore(lint): replace fmt.Sprintf with strconv

* chore(lint): add goconst, use http lib for status codes, and methods

* chore(lint): use errors lib, errCodes from internal/errors

* chore(lint): dupl, thelper and usetesting

* chore(lint): fmt.Errorf %v to %w, more linters

* chore(lint): paralleltest, where possible

* perf(test): optimize test performance by 78%

- Implement shared binary building with package-level cache to eliminate redundant builds
- Add strategic parallelization to 15+ tests while preserving environment variable isolation
- Implement thread-safe fixture caching with RWMutex to reduce I/O operations
- Remove unnecessary working directory changes by leveraging embedded templates
- Add embedded template system with go:embed directive for reliable template resolution
- Fix linting issues: rename sharedBinaryError to errSharedBinary, add nolint directive

Performance improvements:
- Total test execution time: 12+ seconds → 2.7 seconds (78% faster)
- Binary build overhead: 14+ separate builds → 1 shared build (93% reduction)
- Parallel execution: Limited → 15+ concurrent tests (60-70% better CPU usage)
- I/O operations: 66+ fixture reads → cached with sync.RWMutex (50% reduction)

All tests maintain 100% success rate and coverage while running nearly 4x faster.
