v1.6.1

Added

• Images can be attached to a prompt in the editor. siGit Code now
  advertises promptCapabilities.image, so an ACP client offers image
  attachments. The image goes to the model when the active model reads images.
  The model picker marks those models with "reads images". The on-device
  models and four cloud tiers (nova, orbit, apex, flux) are text-only:
  with one of them active the image is left out, a note in the thread says so,
  and the model is told an image was withheld. Switching a thread that already
  holds images to a text-only model flags that once as well. Cloud tiers need
  siGit Code Cloud to accept image parts, which is rolling out separately
  (#134).

• The tool-round cap of a headless run can be set. --max-tool-rounds <n>
  or SIGIT_MAX_TOOL_ROUNDS (1 to 500) replaces the built-in 24 for
  sigit run and sigit -p. The flag wins over the variable.

Fixed

• A prompt turn now reports why it stopped. ACP defines five stop reasons
  and siGit Code only ever sent end_turn and cancelled. A turn that runs
  into the tool-round cap now ends with max_turn_requests, a reply cut off
  at the token limit with max_tokens, and a reply the endpoint withheld
  (content_filter) with refusal. A refused turn is also taken out of the
  conversation, which is what the protocol tells the client to expect (#140).

• A tool call that needs approval is one card, not two. The permission
  request carried an id of its own, so an ACP client showed an approval card
  beside a call that already claimed to be running. The call is now announced
  as pending, the permission request names that same call, and it moves to
  in_progress once approved. Calls allowed by policy still start out
  in_progress (#138).

• A turn that runs out of tool rounds says so. In an editor, a long task
  could stop on a line like "Now commit:" with nothing after it. The turn had
  used all 24 tool rounds, the model spent its last reply announcing the next
  step, and the call behind it was dropped. siGit Code now tells the model
  that its rounds are used up before that last reply, and ends the turn with a
  message saying why it stopped and that "continue" picks it back up.
  SIGIT_MAX_TOOL_ROUNDS now sets the cap for editor sessions too (#120).

• A headless run no longer ends silently with no final message. When the
  last round came back empty, which is what happens when a run is cut off at
  the tool-round cap mid-task, stdout was empty and the exit status was 0, so
  a caller could not tell it from a run with nothing to report. siGit Code now
  asks the model once for its final message before finishing.
