 * (toolchain) Fixed a crash on Windows when precompiling is enabled:

+* (zipapp) Reduced self-contained archive sizes by preserving Python executable
+  symlinks instead of storing each alias as another copy of the interpreter, and
+  by omitting shared `libpython` files from recognized statically linked Astral
