v0.8.2

[0.8.2] - 2026-08-10

Fixed

• requirements.txt drifted from pyproject.toml. It still listed ollama as a
  runtime dependency and was missing best-engine-ai-helper, left over from the
  0.7.0 migration that made best-engine-ai-helper the hard runtime dependency
  and dropped the direct ollama import. ollama is only needed by
  tests/conftest.py for @needs_model tests, so it moves to the dev extra.
