v0.4.2

Changed

• Widened the two agent-tool integration pins so the current majors of both
  backing packages are installable:

  • [spec-tools] → djangorestframework-pydantic-ai>=0.9,<0.11. 0.10.0 adds
    SpecToolset(host=…), the origin that makes DRF's FileField /
    Hyperlinked* fields render absolute URLs off the HTTP path. Nothing here
    uses it — the widening is what lets a consumer pass it.
  • [drf-mcp] → djangorestframework-mcp-server>=0.17,<0.19. 0.18.0 fixes two
    reported crashes: serializer-context providers called positionally
    (TypeError for any provider not leading with view, request) and the
    missing DRF baseline context (KeyError: 'request'). It also carries a
    deliberate break — a provider whose first two parameters are named something
    other than view / request now raises — but that is a change to user
    provider signatures, not to anything this package calls.

  The floors stay at 0.9 / 0.17: neither integration uses new API, so both
  ranges are honestly satisfiable, and a project already pinned to an older
  release isn't forced forward.
