Release v1.6.0

Complete rewrite replacing the OpenAPI-generated client with a clean,
hand-written Go client for the Apache Guacamole REST API:

- Implement client with session-based and token-based auth (NewClient, NewClientWithToken)
- Add CRUD operations for connections, connection groups, sharing profiles,
  users, user groups, active connections, history, and self
- Add LastActive field to User type
- Remove OpenAPI codegen artifacts (guacamole.gen.go, openapi/, flake.nix)
- Add comprehensive test coverage for all resources
