chamnan 1.36.3

A patch on top of 1.36.2: a conversation left open overnight now asks to hand off at its first message.

Fixed and improved

• The first message after a night, in a window left open, asks whether to hand off and clear.
  1.36.2 handed off a conversation resumed after a night, but a window left open overnight starts
  nothing: the next morning's message goes straight in, no session-start hook fires, and every
  request from then on re-sends the whole conversation. That was 5 of 31 measured nights in one
  repository. A new UserPromptSubmit hook applies the same rule (a new date and eight hours or
  more since the last reply), writes the handoff, and tells the session to ask in one line whether
  to hand off and /clear before it starts on the message. "No" carries on and is not asked
  again. Outside a chamnan workspace it still asks and writes nothing. It is silent within a
  sitting, for claude -p dispatches, and after a resume that was already handed off.

Verification

Local suite 7027/7027 on the tagged commit; CI green on all five legs (Ubuntu, macOS, Windows; Python 3.9 and 3.13).

Upgrade

/plugin update chamnan, then restart Claude Code so the new hook is registered.
