* fix: enable IBM watsonx.ai bundle on Python 3.14 ibm-watsonx-ai (1.5.13) and langchain-ibm (1.1.0) added Python 3.14 support upstream on 2026-06-03, so the official 3.14 Docker image no longer needs to silently drop the IBM integration. - Lift the `python_version < '3.14'` markers on ibm-watsonx-ai and langchain-ibm in both the lfx-ibm bundle and langflow-base. - Bump langchain-ibm from `~=1.0.2` to `~=1.1.0`; the 3.14-capable release is 1.1.0, which the old `~=1.0.2` pin excluded. - Regenerate uv.lock: the resolver now forks ibm-watsonx-ai into 1.5.13 for py>=3.11 (incl. 3.14) and 1.3.42 for py<3.11, so 3.10 keeps working while 3.14 gains the integration. watsonx-orchestrate (ibm-watsonx-orchestrate-core/clients) stays gated at <3.14 since upstream 2.10.0 still caps there. * test: stop import-skipping IBM watsonx tests on Python 3.14 The watsonx test modules skipped at module load (pytest.skip with allow_module_level=True) when langchain-ibm / ibm-watsonx-ai failed to import, with comments tying the skip to the upstream <3.14 cap. Now that those deps are importable on 3.14 (this PR's dep bump), the import-based skip can hide real import regressions instead of surfacing them. - test_model_utils.py, test_watsonx.py, test_watsonx_embeddings.py: replace the try/except pytest.skip(allow_module_level=True) guards with direct top-level imports so a missing or broken IBM SDK fails loudly. Drop the now-unused `import pytest` in test_model_utils.py. - src/bundles/ibm/README.md: update the platform note to reflect that the watsonx components are now importable on Python 3.10-3.14. The Db2 tests (test_db2*, test_optional_dependency) are left untouched -- they gate on ibm-db's linux/aarch64 platform exclusion, not the Python version, which is still valid. Validated locally (Python 3.13): 63 tests pass (13 + 50), ruff clean.
