v0.6.4

• When a turn ends while a submitted plan still awaits approval and no approval card was answered, the reply now ends
  with one line saying how to approve: ⏸ Plan rev N is waiting for your approval: type /planmode approve to approve it, or say what to change. It applies on every surface (#19). On Hermes 0.21.6 hermes serve with approvals off,
  gpt-6.1-sol skipped the card in 6 of 6 runs when the task said "do not ask questions" (3 of them with the
  approval_ask lever), and in 0 of 2 without that phrase; on the classic CLI it asked in 3 of 3. The line changes no
  approval decision. It is a pure append to the reply, footer: off turns it off, and subagent or curator turns never
  get it.
• Bound approved snapshot names to 255 filesystem bytes, including non-UTF-8 names, so surrogate-escaped plan
  names no longer refuse edited-plan approval (#54).
