* Fix linting errors Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat(linters): add ineffassign linter This commit adds the `ineffassign` linter to the project's `.golangci.yml` configuration file. The `ineffassign` linter helps identify and flag assignments to variables that are never used, helping to improve code quality and maintainability. Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * Add extra linters Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat(golangci): Add header check - Added goheader check to ensure all files have license headers - Added build tags for "nats" in the .golangci.yml file to include the necessary dependencies for the "nats" package during the build process. - Also, increased the maximum number of issues per linter and the maximum number of same issues reported by the linter to improve the code quality analysis. Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat(.golangci.yml): Add new linters Add the following new linters to the .golangci.yml configuration file: - asasalint - asciicheck - bidichk - contextcheck - decorder - dogsled - errchkjson - errname - execinquery - exportloopref - ginkgolinter - gocheckcompilerdirectives These linters will help improve code quality and catch potential issues during the code review process.
