* feat: add security middleware, graphql apq, and improved linting - Add RateLimit, RequestValidation, and CORS middleware. - Configure middleware chain in API server. - Implement Redis cache for GraphQL Automatic Persisted Queries. - Add .golangci.yml and fix linting issues (shadowing, timeouts). * feat: security, caching and linting config - Fix .golangci.yml config for govet shadow check - (Previous changes: Security middleware, GraphQL APQ, Linting fixes) * fix: resolve remaining lint errors - Fix unhandled errors in tests (errcheck) - Define constants for repeated strings (goconst) - Suppress high complexity warnings with nolint:gocyclo - Fix integer overflow warnings (gosec) - Add package comments - Split long lines (lll) - Rename Analyse -> Analyze (misspell) - Fix naked returns and unused params --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
