Chris Lu 49a7d4ff6a test: pin the LanceDB client, and index before searching
Three from review.

The client's dependencies were unpinned, so an unrelated upstream release
could change what an old commit reproduces. Pinned to the versions this
suite was verified against; the client is as much the thing under test as
the server.

The search was called ANN and was not: without an index LanceDB scans.
The test now builds an IVF_PQ index over 1024 rows first, which is worth
more than the wording fix - an index writes into a directory of the table
that the S3 door has to admit, and that guard has refused a Lance
directory before. It builds, covers all 1024 rows, and searches.

The assertion moved with it. Demanding the exact nearest neighbour was
right for a brute-force scan and wrong for a quantized index, which
answered 0 as readily as 1; both are correct, so the check is now the
neighbourhood.

And the pushdown check accepted any failure. It now requires the refusal
to be the catalog's Unsupported and requires that nothing was left behind,
or, when the client falls back, that the table is complete.
