refactor: remove duplicate .github directory from rust subdirectory

Removed the incorrectly placed .github directory from the loxone-mcp-rust
subdirectory as GitHub Actions workflows should only exist at the
repository root level (.github/workflows/).

This cleanup removes:
- Duplicate CI workflow configurations
- Redundant workflow files (ci.yml, rust.yml, release.yml, etc.)
- Documentation that duplicated repository-level CI information
- Integration test workflows that belonged at the root level

All GitHub Actions workflows are now properly centralized in the
repository root's .github/workflows/ directory, following GitHub's
standard project structure conventions. This eliminates confusion
and potential conflicts between duplicate workflow definitions.
