Prepare for v1.17.1 release

embeddings: restore self-chunking for non-OpenAI models

Re-add _ChunkedOpenAIEmbeddings: for non-Azure models (e.g. Qwen on 'Nova'), send raw
text (check_embedding_ctx_length=False) and split long inputs into character-bounded
chunks, embedding each and length-weighted-averaging into one vector per input, so long
texts never hit the server's context limit. Azure keeps tiktoken (True).

Prepare for v1.17.0 release

Fix four correctness and robustness issues

- connection.py: coerce scalar rows to 1-tuple in _iquery() numpy path
  so single-column structured ndarrays don't break zip(names, row).

- json.py: use integer arithmetic (days/seconds/microseconds) instead
  of float total_seconds() for timedelta serialization to avoid
  precision loss on large durations.

- registry.py: guard numpy import in _normalize_vector_output() behind
  try/except ImportError so non-numpy environments (WASM) can still
  use vector formats like 'list'.

- server.py: use pre-allocated bytearray in _read_pipe_message() to
  avoid quadratic copying, and enforce a 16 MiB size cap to prevent
  unbounded memory growth from malformed length prefixes.

Add PEP 440 pre-release version patching to publish workflow

Parses git tag suffixes (-test, -alpha, -beta, -rc) and patches
pyproject.toml with the corresponding PEP 440 version before building
wheels. Full releases (no suffix) are unaffected.

v1.16.10-rc8: Disable keep-alive on httpx

Fix event loop closed error and add comprehensive UDF dispatch tests

Replace asyncio.run() with _run_with_graceful_shutdown() that drains
pending callbacks before closing the loop, preventing RuntimeError from
httpx/anyio TLS cleanup in async UDFs calling OpenAI/LangChain APIs.

Add 17 unit tests covering graceful shutdown, cancellation timing,
exception propagation, context variable isolation, and concurrent safety.

Add cancellable wrapper for responsive async UDF cancellation

Wraps the inner coroutine in _cancellable_run which polls cancel_event
and raises CancelledError at the next await (~100ms), ensuring vector
UDFs respect disconnect/timeout signals without waiting for completion.

Use thread-per-request for async UDFs instead of shared event loop

The dedicated shared event loop still caused starvation under concurrent
async UDF calls. Switch to the same model used by sync UDFs: each request
gets its own thread with asyncio.run(), eliminating loop contention.
