Built a universal manager and installer for all operating systems and environments. Bumped a lot of versions of things. Still needs deep testing.

+"""Local (never system) uv provisioning into <repo>/.uv/.
+
+uv is a single static binary (no deps, no Python needed). Keeping it inside
+the repo means fast installs + exact-version Python provisioning with zero
+footprint outside the checkout. The run scripts also install into this same
+dir (via the astral installer with UV_INSTALL_DIR) for the no-python
+bootstrap case; util.find_uv() checks here first either way.
