Clean up dead code, fix type errors, and add publish workflow

Remove unused _append_ops_call_method, fix _property_data_from_member
call signature, replace sys.version_info guard with hasattr check for
__buffer__ protocol, fix implicit string concatenations, add msgbus
overrides for 4.0-4.4, add conformance tests, and add publish script.

+## Project Overview
+
+Type stubs generator for the Blender Python API (`bpy`, `mathutils`, `bmesh`, `gpu`, etc.). Stubs are generated by running introspection inside Blender's embedded Python interpreter in `--background` mode. Supported Blender versions: **4.0 through 5.1** (8 versions total).
+
+## Commands
+
+- `uv run poe generate <version>` — Generate stubs for a Blender version (e.g., 5.0)
+- `uv run poe typecheck-stubs <version>` — Type-check generated stubs
+- `uv run poe conformance <version>` — Run conformance tests against stubs
+- `uv run poe check` — Run all checks (format, lint, typecheck, test)
+- `uv run poe test` — Run unit tests
+- `uv run poe format` — Format with black
+- `uv run poe lint` — Lint with ruff
+
+## Code Style
+
+- Format all Python files with **black** after modifying them
+- Use **basedpyright strict** mode — 0 errors is the target
+- Never use `typing.Any` — use concrete types, TypedDicts, Protocols, or unions instead
+- Use raw dict literals for TypedDicts, not explicit constructors (e.g., `{"name": ..., "type": ...}` not `ParamData(name=..., type=...)`)
+
+## Type Checking Rules
+
+- **Never use `# type: ignore`** — fix the actual typing issue instead
+- **Never suppress typecheck rules** with excludes or pyright config overrides — fix the root cause
+- **Never bypass issues with workarounds** — always investigate and fix root causes properly (no empty placeholder stubs, no shims)
+
+## Testing
+
+- **Add tests for every behavior/regex change** — at least two examples per change
+- Test files live in `tests/` and run via `python -m unittest discover -s tests -v`
+
+## Conformance Tests
+
+- **Never modify conformance test files** — they are copied verbatim from Blender documentation
+- When a conformance test fails, fix the stub generation or overrides, not the test
+- Conformance tests live in `conformance/<version>/`
+
+## Architecture
+
+- Stubs are versioned per Blender version: `dist/<version>/` (e.g., `dist/5.0/`)
+- Type overrides are organized per version: `overrides/<version>/<module>.json`
+- Always prefer **introspection** over hardcoding — if something can be discovered at runtime, don't hardcode it
+- Key files: `introspect.py` (data collection), `generate_stubs.py` (stub output), `main.py` (CLI)
+- `introspect.py` runs inside Blender's embedded Python interpreter, which varies by version (e.g., Blender 4.0 uses Python 3.10). Code in this file must be compatible with all supported Blender Python versions.
+
+## Blender Binaries
+
+Cached Blender executables are in `downloads/` (e.g., `downloads/blender-5.1.0-linux-x64/blender`). You can run scripts inside Blender with:
+
+```bash
+downloads/blender-5.1.0-linux-x64/blender --background --python script.py
+```
+
+## Git
+
+- Always add specific files by name — **never use `git add -A` or `git add .`**

 - **Typed `Context.copy()`** — returns a `ContextDict` TypedDict instead of `dict[str, object]`, so unpacking into `context.temp_override(**ctx)` type-checks correctly
 - **Dynamic array types** — `Image.pixels` typed as `bpy_prop_array[float]` (not `list[float]` or `float`)
 - **Zero `Any` usage** — precise types throughout, no `typing.Any` fallbacks
