chore: update lance dependency to v6.0.1

[lance-community]

Summary

• Updates the Lance Rust dependency family from 6.0.0 to 6.0.1 in Cargo.toml.
• Refreshes Cargo.lock with crates.io stable releases for Lance 6.0.1 and related Lance internal crates.
• No [patch.crates-io] Lance overrides are present.

Resolver notes

• Cargo resolved the Lance family and related crates such as fsst, lance-datafusion, lance-datagen, lance-encoding, lance-file, lance-io, and lance-tokenizer from 6.0.0 to 6.0.1.
• Existing manifest constraints for Arrow (58.0.0) and DataFusion (53.0.0) were left unchanged; the lockfile remains on compatible patch releases in those families.

Validation

• cargo fmt --all
• cargo check --manifest-path Cargo.toml
• cargo clippy --manifest-path Cargo.toml --all-targets

Note: the GitHub Actions runner was missing protoc, so protobuf-compiler was installed before rerunning cargo check and cargo clippy successfully.

Triggering tag

• lance-format/lance refs/tags/v6.0.1: https://github.com/lance-format/lance/releases/tag/v6.0.1
