v2 injected the entire plan.md on every turn. pi-tasks tried that and deleted it -- "wallpaper
noise that trains the model to ignore the task block" (CHANGELOG.md:149) -- so follow them: one
transient user message via the context hook, never persisted, and only when the plan went untouched
for 2 turns. Editing the plan resets the clock, the way a task tool call resets theirs. Session
start and session_compact push the WHOLE file back instead, which is where the settled context is
actually needed (pi-goal-x does the same with its post-compaction resync).
That makes an unlimited appendix free: everything under ## Log is durable memory, not working set.
Also: the drafting prompt is sent once with the /goals seed instead of every turn (that re-arming
is why plan mode read as never-ending), the review menu gains "Open in $EDITOR" and loops like
pi-plan's, and the widget shows the active goal's open subtasks so the plan is visibly the task
list. Drops the stale-copy stripping hook, which a non-persisted injection doesn't need.
