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
- Fix f-string lint warning and type annotation for introspect_class
