fix(dist): stop stripping .py sources; wipe payload on NSIS upgrade

Two root causes for the 'imaging extension was built for another version
of Pillow' error users hit after install:

1) cleanup_site_packages ran 'find ... -name "*.py" ! -name "__init__.py"
   -delete' with a comment claiming 'keep .pyc only' — but no compileall
   step exists. Result: the dist shipped __init__.py + .pyd only, missing
   every submodule (Image.py, ImageDraw.py, _version.py, ...). Fresh
   installs were broken; in-place upgrades produced a half-old/half-new
   site-packages. Removed the deletion entirely.

2) NSIS installer extracted over the previous install without cleaning
   python/, app/, scripts/. Upgrades left stale files (old PIL/_version.py
   next to new PIL/_imaging.pyd) which raised the Pillow ABI mismatch.
   Wipe those subtrees before File /r, preserving config.yaml at the
   install root.

-Version is tracked in two files that must be kept in sync:

-- `pyproject.toml` - `[project].version`
-- `media_server/__init__.py` - `__version__`

+Version flow:
+1. `git tag v0.3.0` → CI reads the tag
+2. Build scripts stamp `pyproject.toml` with the clean version via `sed`
+3. `pip install` bakes the version into package metadata
+4. `importlib.metadata.version("media-server")` reads it at runtime
+
+When bumping the version for a new release, only `pyproject.toml` needs to be updated.
 
 **Important:** After making any changes, always ask the user if the version needs to be incremented.
