Add config package with build-tag-switched dev/prod environments, structured logging via zerolog, Taskfile for dev workflow, golangci-lint config, testutil package, and improved DB setup with proper SQLite pragmas and cleanup. Rename sqlc output package from gen to repository. Switch to allowlist .gitignore, Alpine+UPX+scratch Dockerfile, and CI pipeline with test/lint gates before deploy.
