Python 3.15.0 was released on 2026-10-09, and `requires-python = ">=3.10,<3.15"` made pip refuse to install DataJoint on it. The cap moves to `<3.16` (in `[project]` and in the pixi workspace), the 3.15 classifier is added, and a `test-py315` pixi environment joins `test-py310` and `test-py314`. The Linux and Windows test matrices gain a 3.15 leg; 3.14 stays in both. The 3.10 floor is unchanged; dropping it is planned for 2.4. One dependency is not ready for 3.15. `deepdiff` 9.x requires `cachebox>=5.2,<6`, and no cachebox 5.x release ships 3.15 wheels. Its sdist builds with PyO3 0.27, which supports CPython only up to 3.14, so building from source fails too. Until deepdiff accepts cachebox 6 (which does ship 3.15 wheels), installing on 3.15 fails at cachebox, and the new 3.15 CI legs will fail while installing dependencies. Every other package in the test environment has 3.15 wheels on Linux, macOS and Windows. `pixi.lock` is regenerated. Besides the new environment it adds what the committed lock was missing: the `test-py310` and `test-py314` environments, and `packaging` in the default environment. Part of #1569.
deepdiff 9.x requires `cachebox>=5.2,<6`. No cachebox 5.x release ships Python 3.15 wheels, and its sdist cannot be built for 3.15 because it uses PyO3 0.27, which supports CPython only up to 3.14. So on 3.15, installing DataJoint fails at cachebox. deepdiff 8.6.x is pure Python and depends only on orderly-set. DataJoint uses deepdiff only for `DeepHash` in the three-part `make` check in autopopulate, which works the same on 8.6. The bound applies only on 3.15 and later; other Python versions keep resolving the newest deepdiff. Drop it once deepdiff accepts cachebox 6, which ships 3.15 wheels. With this bound the full test suite passes on Python 3.15.0, integration tests included, and every compiled dependency in the test set has 3.15 wheels for Linux, macOS and Windows. Part of #1569.

Part of #1569. This is the Python 3.15 half; dropping 3.10 follows in 2.4.
