Add bounded compiler-only worker history views

 ## Context delivery
 
+`worker_view` reads the attached worker's history, or the worker's own history. `Ctrl+O` expands bounded Markdown with paired calls/results and background-control references. Review and stop contexts include the same view; routine progress and receipts stay short. Saved launches and watches do not establish current job status: check the native owner before waiting or intervening. This uses VCC's compiler only, without loading its extension runtime. <!-- Pi/OpenAI -->
+
 New injected `[pi-goals]` prompts display as a compact notice; `Ctrl+O` expands the full text. This changes only the display: the original prompt still reaches the model once through normal role preparation. Older notices without a saved display entry remain expanded. — Pi/OpenAI
 
-Startup, attachment/resume, session restore, successful compaction and changed requirements restore the active plan above Log at the next ordinary prompt. This includes current preferences and User voice, but leaves historical Log on disk. Routine context and requested reviews quote unfinished or unreviewed goal lines. After eight unchanged turns, the next ordinary prompt carries an upkeep reminder with its reason, those goal lines and the plan path. It omits preferences, role prose and rotating quotations. Reviewed, cancelled and paused work receives no periodic upkeep; manual ticks remain unreviewed. A fresh plan refresh replaces pending upkeep; edits, pause, exit and session navigation invalidate obsolete reminders. Failed or cancelled compaction does not schedule a refresh. Missing plans are retried. Compaction still uses Pi's configured threshold.
+Startup, attachment/resume, session restore, successful compaction and changed requirements restore the active plan above Log at the next ordinary prompt. This includes current preferences and User voice, but leaves historical Log on disk. Routine context and requested reviews quote unfinished or unreviewed goal lines. After eight unchanged turns, the next ordinary prompt carries an upkeep reminder with its reason, those goal lines and the plan path. It omits preferences and role prose; occasional rotating perspective quotations accompany supervision upkeep. Reviewed, cancelled and paused work receives no periodic upkeep; manual ticks remain unreviewed. A fresh plan refresh replaces pending upkeep; edits, pause, exit and session navigation invalidate obsolete reminders. Failed or cancelled compaction does not schedule a refresh. Missing plans are retried. Compaction still uses Pi's configured threshold.
 
 Plan-change notices direct the agent to read the current file, including changed constraints or a final cancellation. Only our own pending notice is coalesced; unrelated queued input does not suppress it. The editable hourly `schedule_task` check-in remains separate. It uses an explicit prompt action, session scope and a short one-line wake that reads the current attached plan. Inspect recurrence with `/schedules all`; change the interval through `manage_scheduled_task` without resending the prompt. Pause disables the owned check-in and retains its prompt/interval; resume may enable only the unchanged job recorded by that pause. Disabled jobs survive reload.

 You can be playful: let the humor come from what actually happened. Avoid repeating recent jokes, nicknames or kaomoji; plain updates are welcome too. No forced cheerfulness or novelty. If supervision gets repetitive, step back and change your approach. Keep it brief and aimed at the goal, not another reporting chore.
 You can speculate and brainstorm around uncertainty or unexpected results. Label guesses as guesses, consider alternative explanations, and look for a useful way to tell them apart. Keep exploration brief, open-minded and fun: take a step back, play with surprising ideas, question the current framing, and enjoy exploring the broader perspective while staying connected to the agreed goal.
