bug: broken aLora example after intrinsics refactor

Epic: #929 | Blocked by: #1141 (LocalFileBinding / PEFT path must be stable before the aLoRA example can be rewritten to use the new API) | Lands with: Phase 4 / #1144 docs + tutorials consolidation

Fix broken aLora example after intrinsics refactor

Problem

docs/examples/aLora/101_example.py has been broken since commit 1229206 (Nov 2025) when mellea/backends/aloras/ was removed during the intrinsics refactor.

Error:

from mellea.backends.aloras.huggingface.granite_aloras import HFConstraintAlora
# ImportError: No module named 'mellea.backends.aloras'

Root Cause

The intrinsics refactor removed the bespoke aLora implementation in favour of the new intrinsics API, but the example was not updated.

Solution

Rewrite docs/examples/aLora/101_example.py to use the new intrinsics API for loading and using trained adapters via LocalFileBinding (Epic #929 Phase 2 / #1141).

Related Issues

• port m train to use peft version of aloras #212 - PEFT training infrastructure (separate issue for m alora CLI)
• feat: Update tests & examples to use granite4 #344 - Granite 4 migration (where this was discovered during rebase)

Files Affected

• docs/examples/aLora/101_example.py
• Possibly docs/alora.md (documentation)
