v0.1.16

Memory stays clean, and content changes can be previewed on real briefs.

• No forced writes: the wake no longer has to end with memory_add or
  note_write, and the stop check no longer asks for a "why" note.
• memory_add is a dream-only tool. note_write, strategy_write and memory_add
  refuse per-wake refs (r58) with stale_ref; note topics starting with a date
  are refused with dated_topic.
• Memory and notes load only in the mode they were written in (dry run or
  live), using the agent's actions as the clock.
• The trace keeps each brief, every draft and the critic's verdict.
  wake-export --briefs and the live-only briefs suite replay recent briefs
  through the current writer and critic.

No schema change. The live template's research-focus line no longer asks for
memory_add.
