lancedb-gatefixer[bot] 85daeb27cb fix: isolate remote table checkout state per handle (#4310)
## Cause

`RemoteDatabase` cached and returned the same `Arc<RemoteTable>` for
every open of a table on one connection. Checkout mutates version and
freshness state on that shared object, so pinning one handle also pinned
the others.

## Fix

Cache the table's server version rather than its mutable handle. Each
`open_table` now creates its own `RemoteTable` with independent
checkout, schema cache, and freshness state.

## Validation

- Added a cache-enabled regression test that failed before the fix:
pinning one handle changed another handle's reported version. It now
verifies a write through the independent handle succeeds.
- `cargo test --quiet --features remote -p lancedb --lib
remote::db::tests` (90 passed)
- `cargo check --quiet --features remote --tests --examples`
- `cargo clippy --quiet --features remote --tests --examples`
- `cargo fmt --all`

Fixes #4296
