* ci: try Python 3.15 release candidate (DRAFT)
Point the repo's .python-version at 3.15 so every workflow that reads
python-version-file runs on the 3.15 release candidate (allow-prereleases
is already enabled across all workflows). Add the 3.15 trove classifier
and bump scipy>=1.18.1, which is the first scipy with cp315 manylinux
wheels, so uv installs it as a wheel rather than building from source.
Rebuilt on current master: the earlier version of this PR edited the
per-workflow `python-version: 3.14` lines, but master has since moved
the interpreter to a single `.python-version` file, so the change is now
a one-line switch there.
Purpose is to document which dependencies/tests are not yet 3.15-ready.
Must stay DRAFT until Python 3.15 GA (early October). Requested in #15081.

* ci: switch default Python to free-threaded 3.14t
Change the interpreter used across CI workflows from 3.14 to the
free-threaded build 3.14t to surface which dependencies and tests are
not yet free-threading compatible. Opened as DRAFT for documentation
purposes per maintainer request (#15081).
* ci(3.14t): gate opencv-python into optional 'cv' group + skip cv2 files
opencv-python has no cp314t wheel yet and fails to build from source under
free-threaded 3.14t (CMake), blocking uv sync for every job. Move it to an
optional [dependency-groups] cv group so the ft CI installs everything else
and runs pytest-run-parallel on the pure-Python algorithms. Skip the 20 files
that import cv2 (computer_vision augmentations, data_compression PSNR, and the
mostly-cv2 digital_image_processing/ tree). Re-fold once a cp314t wheel ships
(upstream: opencv/opencv#27933).

* ci(3.14t): add --ignore-gil-enabled so sklearn/xgboost imports don't abort the run
* ci(3.14t): gate qiskit into an optional group like opencv
qiskit re-enables the GIL under free-threaded CPython and the team is still scoping free-threading support (Qiskit/qiskit#16893), so move it out of the core deps into an optional 'quantum' group and ignore the one algorithm that imports it (quantum/q_fourier_transform.py) in the 3.14t test run. Mirrors the existing opencv 'cv' carve-out. Per cclauss: default all workflows to 3.14t except tests depending on OpenCV or Qiskit.

* ci: single-source 3.14t via .python-version; declare Free Threading :: 2 - Beta
Un-ignore .python-version and pin it to 3.14t, then point all four
workflows at python-version-file: .python-version so the free-threaded
interpreter is selected from one place. Also add the
'Programming Language :: Python :: Free Threading :: 2 - Beta' trove
classifier to document our free-threaded support status per
https://py-free-threading.github.io/porting/#define-and-document-thread-safety-guarantees
