build(trim): autogluon==1.5.0 blocks support for Python 3.14

[AlessandroPomponio]

🐛 Issue

ado-trim depends on autogluon==1.5.0, which in turn requires pyarrow<21.0.0. However, Python 3.14 support in pyarrow only starts from version 22.0.0.

This creates an unsatisfiable dependency constraint for Python 3.14:

• autogluon==1.5.0 → requires pyarrow<21.0.0
• Python 3.14 → requires pyarrow>=22.0.0

As a result, pip cannot resolve dependencies when installing ado-trim with Python 3.14.

💥 Impact

• ado-trim cannot be installed on Python 3.14 using standard dependency resolution
• Users attempting installation will encounter version conflicts in pyarrow
• No practical workaround exists without modifying dependency constraints or forking upstream packages

✅ Current status

• Python 3.14 support is blocked by upstream constraints in autogluon
• Waiting for a new autogluon release that relaxes or updates its pyarrow dependency

🔧 Proposed action

Once autogluon supports a pyarrow version compatible with Python 3.14:

1. Upgrade autogluon in ado-trim
2. Validate dependency resolution with Python 3.14
3. Update CI/test matrix run ado-trim tests on Python 3.14
4. Verify end-to-end functionality

✅ Done when

• autogluon releases a version compatible with pyarrow>=22.0.0
• ado-trim installs successfully on Python 3.14 via PyPI
• CI passes with Python 3.14 enabled
• Python 3.14 support is verified and documented in ado-trim
