Add rna_type/bl_rna, GeometrySet, bpy.ops typing, publish task, and README updates

- Add rna_type and bl_rna as readonly properties on bpy_struct (fixes fake-bpy-module#419)
- Discover non-RNA C classes in bpy.types like GeometrySet (fixes fake-bpy-module#436)
- Introspect bpy.ops operator wrapper with poll(), idname(), get_rna_type(), bl_options
- Handle builtin name shadowing (e.g. bpy.ops.object) with builtins. qualification
- Add poe publish task for building and publishing to PyPI
- Update project URLs to Gitea, improve generated README, add disclaimer

+## Generating Stubs
+
+To generate stubs for a specific Blender version, run:
+
+```bash
+uv run poe generate 5.1
+```
+
+This will automatically download the corresponding Blender executable and run the introspection and stub generation process. You can also type-check the generated stubs:
+
+```bash
+uv run poe typecheck-stubs 5.1
