Bump version: 0.37.1-beta.3 → 0.37.1

## Summary

`opendal 0.58.1` (the version pulled in transitively via Lance) already
ships
`goosefs-sdk 0.1.9`, which includes the upstream fix for the 0.1.6
compile
break. The explicit version pin that lancedb has been carrying since the
GooseFS feature was introduced is therefore no longer necessary and is
now
redundant work to maintain.

## Changes

- Remove the direct `goosefs-sdk` dependency from
`rust/lancedb/Cargo.toml`
(it was pinned to `=0.1.9` with a comment referencing the 0.1.6 compile
  break).
- Remove the `dep:goosefs-sdk` entry from the `goosefs` cargo feature,
since
  no source file in lancedb imports the crate directly.
- Refresh `Cargo.lock`; `goosefs-sdk 0.1.9` now resolves transitively
through
  `lance` → `opendal 0.58.1`.

## Verification

- `cargo fmt --all` — clean
- `cargo check --features remote,goosefs --tests --examples` — passes
- `Cargo.lock` confirms `goosefs-sdk 0.1.9` is still resolved (now
transitively), so the `goosefs` feature continues to enable the same set
of
  Lance/IOPaths as before.

## Backwards compatibility

No public API changes. The `goosefs` cargo feature still activates
`lance/goosefs`, `lance-io/goosefs`, and
`lance-namespace-impls/dir-goosefs`,
and the same `goosefs-sdk 0.1.9` version is selected by the resolver.

+//!
+//! The target set is fixed at the start, so generations created *during* the
+//! checkpoint are ignored. That is what lets it terminate under write load,
+//! and what makes it best-effort: it converges the fresh tier as of some
+//! instant. Idempotent, abandonable at any point, safe on a cadence.
+//!
+//! No liveness bound — the caller owns the deadline. The compactor pool is
