v0.2.7

Added

• Models without image support can now understand images through visual
  assistance. LoomRouter detects vision capability from the model catalog
  and, when needed, asks a configured vision model to describe the image
  before continuing the original request. Models that already support images
  keep receiving them directly.

Fixed

• DeepSeek models on OpenCode Go can complete tool-assisted image turns
  without entering a reconnect loop. LoomRouter now sends the portable
  Responses shape expected by the gateway, including empty side-calls,
  function tools, reasoning items, parallel calls and their outputs.
• Tool results stay paired with their calls across stateless routed turns.
  Internal item identifiers and ChatGPT-only metadata are removed, structured
  outputs are converted to portable text, and interleaved assistant or
  developer context no longer separates a call from its result.
• Rejected upstream requests now log safe structural diagnostics. Pairing,
  ordering and reasoning-shape counts identify protocol mismatches without
  exposing prompts, tool arguments, outputs or call identifiers.
