Improve lint target to check and fix Go version mismatches

Summary

Enhanced the make lint target to automatically detect and fix Go version mismatches between the installed golangci-lint and the project's Go version requirements. This prevents the error "Go language version used to build golangci-lint is lower than the targeted Go version" that was encountered when golangci-lint was built with an older Go version than specified in go.mod.

The updated logic:

1. Checks if golangci-lint exists, installs if missing (existing behavior)
2. NEW: Compares the Go version used to build golangci-lint with the project's required Go version
3. NEW: Automatically reinstalls golangci-lint with the correct Go version if there's a mismatch
4. Uses GOTOOLCHAIN to ensure installation with the project's required Go version

Review & Testing Checklist for Human

3 items - needs careful testing due to shell complexity

• Test version mismatch scenario: Manually install golangci-lint with an older Go version and verify make lint detects and fixes the mismatch
• Verify cross-platform compatibility: Test the shell logic works on different systems (the regex parsing and sort -V command might behave differently)
• Test edge cases: Verify behavior when golangci-lint version output is malformed or when version parsing fails

Recommended Test Plan

1. Install golangci-lint with Go 1.23: GOTOOLCHAIN=go1.23.0 go install github.com/golangci/golangci-lint/cmd/[email protected]
2. Run make lint and verify it detects the mismatch and reinstalls correctly
3. Run make lint again to ensure it doesn't reinstall unnecessarily

Notes

• The shell logic is more complex than ideal - version parsing uses regex and string manipulation that could be brittle if golangci-lint changes its output format
• Uses sort -V for version comparison which should work on most systems but worth testing
