v4.0.0

4.0.0 (2026-09-11)

⚠ BREAKING CHANGES

• compat: the minimum DeepSeek Harness version is now 0.1.5-rc.1
  (engines.dsh raised from >=0.1.1-rc.2). The 0.1.1-rc.2 line is no longer
  supported. It predates every harness contract this plugin now depends on:
  the object-rooted tool-schema requirement, the agent-preset/selected
  session event, the persona prefix/suffix split, and the separately
  loadable list-agents row. Deployments still on 0.1.1-rc.2 must upgrade the
  harness before upgrading this plugin.

  This is a version-signalling release: 3.3.2
  already shipped the same compatibility work, but numbered it as a patch,
  which understated the break. 4.0.0 is otherwise identical to 3.3.2.
