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

-## Usage
+## Features
 
-Install alongside your Blender addon project for type checking with mypy, pyright, ty or your IDE.
+- Full Blender API coverage (`bpy`, `mathutils`, `bmesh`, `gpu`, `gpu_extras`, `bpy_extras`, `freestyle`, `aud`, `blf`, `bl_math`, `imbuf`, `idprop`)
+- Accurate collection types (`BlendDataObjects` instead of generic `bpy_prop_collection`)
+- Readonly `@property` decorators for RNA attributes
+- Typed context members (`bpy.context.active_object`, `selected_objects`, etc.)
+- Constructor signatures for `mathutils`, `gpu`, and other C extension types
+- Literal enum types instead of plain `str`
+- Zero `typing.Any` usage
+- 0 errors in basedpyright strict mode

+## Usage
 
 ```python
 import bpy
 
-# Your IDE now provides autocomplete and type checking
 obj: bpy.types.Object = bpy.context.active_object
+obj.location.x = 1.0
+
+bpy.data.objects.new("Cube", bpy.data.meshes.new("Mesh"))
