Release v1.1.1: refactor Go codebase and documentation

[cerede2000]

v1.1.1 — maintainable Go codebase and documentation

What changed

• refactors the former 2,200-line src/main.go into focused files without changing runtime behavior:
  • config.go: profile parsing, validation, and reload;
  • docker_discovery.go: Unix client, discovery cache, and event loop;
  • policy.go: Docker route classification, authorization, scope enforcement, and response filters;
  • proxy.go: HTTP proxy handling and healthcheck;
  • types.go: shared configuration and Docker data types;
  • main.go: application wiring only.
• makes README.md the complete English default documentation;
• adds the complete French translation in README.fr.md, with bidirectional language links;
• documents the local HTTP-to-Unix-socket security model and links the Docker Scout report.

Why

The separation keeps the current least-privilege behavior intact while creating clean boundaries for future engine adapters, such as Podman, without duplicating authorization and container-scope logic.

User impact

No configuration, endpoint, image, or authorization behavior changes. Existing profiles and deployments remain compatible.

Validation

• gofmt -w src/*.go
• git diff --check
• go test -race ./...
• go vet ./...
