[BUG] Build Failure: Python 3.14 incompatibility due to outdated pyo3 in jsonschema-rs #111

Description

When installing or running tests on Python 3.14, the dependency build fails. The transitive dependency jsonschema-rs (v0.29.1) fails to compile from source. Maturin fails to build the native library because the PyO3 version used by jsonschema-rs (v0.23.4) does not support Python 3.14 yet (maximum supported is Python 3.13).

SkillSpector's pyproject.toml declares:

requires-python = ">=3.12,<3.15"

Which indicates support for Python 3.14, but the build environment fails on 3.14.

Error Logs

error: the configured Python interpreter version (3.14) is newer than PyO3's maximum supported version (3.13)
  = help: please check if an updated version of PyO3 is available.
Current version: 0.23.4
  = help: set PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to suppress this check and build anyway using the stable ABI
warning: build failed, waiting for other jobs to finish...
maturin failed
  Caused by: Failed to build a native library through cargo

Remediation

1. Adjust the python requirement range in pyproject.toml to requires-python = ">=3.12,<3.14" to accurately reflect Python 3.13 as the upper limit until PyO3/jsonschema-rs is updated.
2. Or document a workaround to run PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 uv pip install . on Python 3.14.
