Upgrade rattler dependency family

[jezdez]

Summary

Upgrade the rattler dependency family separately from the experimental conda-fleet API work.

This bumps the direct rattler-family requirements in Cargo.toml:

• rattler: 0.43 -> 0.45
• rattler_cache: 0.8 -> 0.10
• rattler_conda_types: 0.46 -> 0.47
• rattler_lock: 0.30 -> 0.31

Cargo.lock was regenerated with cargo generate-lockfile.

Compatibility Change

rattler_cache::PackageCache::get_or_fetch_from_path now takes a third optional cache reporter argument, so the bundle-cache path now passes None explicitly.

Why

PR #45 needs the newer rattler stack for downstream integration compatibility. Splitting the dependency alignment into this PR keeps the conda-fleet API review focused on API shape and install orchestration behavior.
