Bundle AsyncTI4 resources in PyPI artifacts and support installed-package resource paths

[Copilot]

analyze() failed in PyPI installs because AsyncTI4 resources were not shipped in the distribution and path resolution only targeted repo-style layouts. This change makes packaged installs self-contained and resolves resources from both source and installed contexts.

• Packaging: ship full AsyncTI4 resources

  • Updated pyproject.toml to include data/TI4_map_generator_bot/src/main/resources in both build targets:
    • wheel: force-include into ti4_rules_engine/data/.../resources
    • sdist: include full resources tree (not only resources/data)

• Runtime path resolution: support packaged layout

  • Updated _data_paths.py to search multiple candidate locations:
    • data/TI4_map_generator_bot/src/main/resources (repo checkout)
    • ti4_rules_engine/data/TI4_map_generator_bot/src/main/resources (installed package)
  • Error messaging now reflects both expected layouts.

• Regression coverage

  • Added focused tests for _locate_asyncti4_resources_dir() covering both repo-style and packaged-style directory structures.
