ci(release-local): stop macOS builds from picking up a broken system Python

[AnishSarkar22]

actions/setup-python's macOS interpreter has SQLite extension loading compiled out, so uv could grab it instead of its own capable managed Python during uv sync. sqlite_vec needs enable_load_extension, so the frozen api/worker binaries crashed on startup on every Mac. Drop the redundant setup-python step and pin UV_PYTHON_PREFERENCE=only-managed so uv never considers a PATH-found interpreter.

High-level PR Summary

This PR fixes a macOS build issue where the frozen API and worker binaries were crashing on startup. The problem occurred because actions/setup-python provides a Python interpreter with SQLite extension loading disabled, which is required by sqlite_vec. The fix removes the redundant setup-python step and sets UV_PYTHON_PREFERENCE=only-managed to ensure uv always uses its own managed Python interpreter with SQLite extension support enabled.
