chore: update lance dependency to v8.0.0-beta.2 (#3500)

Updates Lance dependencies to v8.0.0-beta.2 across the Rust workspace
and Java lance-core metadata.

The update was generated with ci/update_lance_dependency.py and required
no compatibility code changes.

Lance tag:
https://github.com/lance-format/lance/releases/tag/v8.0.0-beta.2

## ⛔ Merge blocker: legal review required

This bump pulls in a new transitive **dev/profiling** dependency chain
`inferno v0.11.21` → `pprof v0.15.0` → `lance-testing`, and `inferno` is
licensed **CDDL-1.0** (copyleft). To get `cargo-deny` green, `CDDL-1.0`
was added to the `deny.toml` allow list.

**Do not merge until legal has reviewed and signed off on allowing
CDDL-1.0.** The dependency is dev/test-only and not distributed, but the
allow-list addition still requires legal approval per our policy.
