- Add `knime/label/nightly` channel - knime-python-versions: add 5.12.* (was implicit) - knime-extension-bundling: 5.5.* -> 5.12.* - Drop explicit python pins - Switch `rdkit` from conda (`rdkit *`) to **pypi** (rdkit-pypi wheels). Reason: conda-forge's rdkit builds are py3.10/3.11/3.14 across platforms; none satisfy 5.12's py3.13 strict pin. The PyPI rdkit wheels have full py3.13 coverage on win/linux/macOS.

What
Updates the extension's bundled Python environment to the KNIME 5.12 / Python 3.13 stack:
knime-python-versions = 5.12.*andknime-extension-bundling = 5.12.*python = "*"(the runtime is selected byknime-python-versions)knime/label/nightlychannel (5.12 is not on the stableknimechannel yet)--update-sites-version 5.12Where older dependency pins blocked Python 3.13, they were updated to the
nearest compatible versions; extensions still using a legacy conda
env.ymlwere migrated to
pixi.toml.Why
KNIME Analytics Platform 5.12 ships Python 3.13. Extensions pinned to the older
stack won't resolve against it. This bump keeps the extension installable on
5.12 and pulls in the patched dependency tree (notably fewer known CVEs).
Validation
The environment locks cleanly with pixi and builds on the KNIME community
