• CI: add 3.15 to the test matrix
• setup.py: add the Programming Language :: Python :: 3.15 classifier

The code needs no change.

One addition to the workflow

The test job's setup-python step now sets allow-prereleases: true. From the sandbox I could not confirm that a final 3.15.0 is available to setup-python; the only build I could get was 3.15.0b4. With the option, the job uses a pre-release only when a version has no final release, so it is harmless for the other versions. If 3.15.0 final is out, the line can simply be dropped.

Verification

Run locally on CPython 3.15.0b4:

• python tests.py: 360 tests pass, also with -W error::DeprecationWarning
• python property_tests.py: 26 tests pass
• python ext_tests.py tests.js: 87 tests pass
• python -m build succeeds

Not checked on 3.15: the stub and docs jobs, which CI runs on 3.13 only.

Two things I ran into that are not part of this PR:

• On 3.15.0b4, Hypothesis's native module did not import until I copied it to the file name that beta expects. This looks like a beta-only naming difference rather than a problem in this project, but the 3.15 CI job is where it would show up if not.
• argparse.FileType, which jsonpatch_cli.py uses for its inputs, raises a PendingDeprecationWarning on 3.15 (as on 3.14). The tests pass because it is not a DeprecationWarning yet.
