lancedb-gatefixer[bot]andXuanwo 6777a40dc2 fix: support remote tables in storage root (#3881)
## Summary

- allow `db://` to select the remote storage root when a host override
supplies the endpoint
- preserve the empty `x-lancedb-database` header used by the legacy
clients for root storage
- reject root-storage connections without a host override before
constructing an invalid Cloud URL
- document the supported URI and cover both accepted and rejected
configurations

## Root cause

The shared Rust remote URL parser required every `db://` URI to contain
a host. That validation was introduced when the Node and Python clients
moved to the Rust implementation, but the legacy Node client
intentionally treated the empty host in `db://` as the storage-root
selector.

## Validation

- `cargo fmt --all`
- `cargo test --quiet --features remote -p lancedb
test_connect_remote_storage_root`
- `cargo check --quiet --features remote --tests --examples`
- `cargo clippy --quiet --features remote --tests --examples`
- `cargo test --quiet --features remote --tests`

Fixes #1944
