Astral Benchmarks python-build-standalone as Fastest CPython Distribution

Astral's Charlie Marsh shared benchmarks showing python-build-standalone is the fastest CPython distribution—10% faster than Homebrew and 18% faster than official Docker images—thanks to Clang, PGO/LTO, BOLT, and static linking; making it uv's default is the team's goal.
