Groundskeeper 0.18.0

Added

• After-dark guard: a plan that stopped to charge heads back out by itself when the battery is full, at any
  hour. If that happens between sunset and sunrise at your yard, the panel now sends it home (Return to dock, the
  default; or notify only, or ignore, in Settings → Run rules), not when you sent it out yourself. On a real mow,
  Return to dock ended the plan; the next schedule window starts it again. Like every guard it only sends a command
  while control is on.

Changed

• The AI assistant server runs on MCP's 2.x library (mcp 2.3). Nothing changes in what an assistant can do or
  see; the server now reports the panel's version and speaks the newer protocol revisions. Existing tokens and
  connect snippets keep working.
