Add Python 3.14 compatibility #166

Open

Description

@nikolaymatrosov

Currently, the package metadata specifies support up to Python 3.13:

classifiers = [
    "Programming Language :: Python :: 3.9",
    "Programming Language :: Python :: 3.10",
    "Programming Language :: Python :: 3.11",
    "Programming Language :: Python :: 3.12",
    "Programming Language :: Python :: 3.13",
]

With Python 3.14 now available, installation and usage may be blocked or untested in environments that default to 3.14.

Request

Please:

  1. Add Python 3.14 to the supported classifiers
  2. Run CI against Python 3.14
  3. Confirm compatibility or document any blockers

    Currently, when adding the SDK as a dependency, the YC serverless function builder attempts to install all of its transitive dependencies and fails while building a wheel for grpcio-tools.

    One possible solution is to upgrade grpcio-tools to version 1.75.1, which includes prebuilt wheels for Python 3.14 and should resolve the issue.
