chore: fix golangci-lint violations across codebase

     Add golangci-lint to CI pipeline and resolve linting issues:

     - Add golangci-lint target to Makefile for CI enforcement
     - Disable fieldalignment checker in .golangci.yml
     - Fix unchecked error returns with proper error handling
     - Replace fmt.Fprintf + os.Exit patterns with log.Fatal
     - Add proper defer cleanup with error checking
     - Fix unused parameters and mark with nolint directives
     - Improve error message formatting consistency
     - Remove unused context parameters
     - Rename FossaError to Error for naming convention
     - Fix constant naming (FossaTeamAdmin) and type declarations
     - Replace fmt.Printf with log.Printf for consistency
     - Address gosimple and staticcheck warnings

     This improves code quality and establishes baseline for automated
     linting in the CI pipeline.
