fix: honor IndexAsyncio config overrides

[pragnyanramtha]

Root cause

Pinecone.IndexAsyncio(...) and AsyncPinecone.IndexAsyncio(...) accepted **kwargs, but the compatibility factories ignored those values when constructing AsyncIndex. As a result, calls such as pc.IndexAsyncio(host=..., ssl_verify=False) still used the parent client's default ssl_verify=True, which blocks proxy/local setups that need certificate verification disabled.

Change

• Build the AsyncIndex constructor kwargs from the parent client defaults and overlay explicit supported data-plane kwargs.
• Reject unknown kwargs instead of silently ignoring them.
• Add regression coverage for both sync and async compatibility factories forwarding ssl_verify=False.

Validation

• uv sync --group dev --no-install-project
• PYTHONPATH=. .venv/bin/python -m pytest tests/unit/test_pinecone_class.py::TestPineconeIndexAsyncioDelegate tests/unit/test_async_pinecone_backcompat.py -q (35 passed, 1 pytest config warning because pytest-timeout was not installed by the no-project source-tree run)
• PYTHONPATH=. .venv/bin/python -m ruff check pinecone/_internal/indexes_helpers.py pinecone/_client.py pinecone/async_client/pinecone.py tests/unit/test_pinecone_class.py tests/unit/test_async_pinecone_backcompat.py
• PYTHONPATH=. .venv/bin/python -m ruff format --check pinecone/_internal/indexes_helpers.py pinecone/_client.py pinecone/async_client/pinecone.py tests/unit/test_pinecone_class.py tests/unit/test_async_pinecone_backcompat.py
• PYTHONPATH=. .venv/bin/python -m mypy --strict pinecone/_internal/indexes_helpers.py pinecone/_client.py pinecone/async_client/pinecone.py

Note: I initially tried uv run pytest ..., but stopped it after it spent roughly 12 minutes compiling the native Rust extension through maturin before reaching pytest. The final checks above run from the source tree to keep validation focused on this Python-only compatibility change.

Fixes #465.

Note

Medium Risk
Changes behavior of the IndexAsyncio backcompat factories to apply/validate kwargs, which could break callers that previously passed (and had ignored) unsupported parameters. Limited to client construction-time configuration, with added unit coverage for the new semantics.

Overview
Fixes the backcompat IndexAsyncio factories on both Pinecone and AsyncPinecone to actually honor explicit data-plane overrides (e.g. ssl_verify=False) instead of always using parent-client defaults.

Introduces apply_index_kwargs_overrides() in indexes_helpers to merge supported overrides and raise TypeError on unknown kwargs (rather than silently ignoring them), and adds regression tests covering override forwarding and unknown-kwarg rejection.
