Add local uv.toml to override exclude-newer for Mojo 1.0.0b2 toolchain

The global uv config sets exclude-newer = "30 days", which filters out the
pinned mojo==1.0.0b2 toolchain and its Modular deps (all published 2026-06-18),
breaking the documented `uv pip install "mojo==1.0.0b2"` flow. Override the
cutoff per-package so the install resolves without extra flags.
