v0.26.1

Changed

• Widened the two agent-tool integration pins, matching
  django-pydantic-agent 0.4.2, 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'). Its one deliberate
    break — a provider whose first two parameters are named something other than
    view / request now raises — applies 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.
