chore: update golangci-lint configuration and improve CI workflow documentation

- Increased thresholds for funlen and lll linters to accommodate complex functions.
- Added exclusions for dupl linter in specific files and directories to reduce false positives.
- Updated CI workflow documentation to clarify triggers and requirements for SonarCloud analysis.
- Removed unnecessary linter directives in several files for improved readability.
