feat: add AAC YAML support, replace Node.js CLI

Add native support for Analytics-as-Code (AAC) YAMLs in the Python SDK,
replacing the experimental Node.js-based gdc CLI with a pure Python
implementation using the gooddata-code-convertors WASM package.

- New aac.py module with individual conversion functions and workspace-level
  load/store for all supported AAC types (datasets, metrics, visualizations,
  dashboards, plugins, attribute hierarchies)
- Rewritten gdc CLI: no npm/Node.js dependency, reads gooddata.yaml directly
- Config alignment: SDK now understands VSCode plugin config fields
  (workspace_id, data_source, source_dir)
- Extended CatalogWorkspaceService with load_and_put_aac_workspace and
  get_and_store_aac_workspace methods
- 24 tests covering conversions, format detection, config parsing, and CLI
