Learn: distill this session into the skill library

Review the conversation so far and distill what is worth keeping — through the standard proposal chain, never by writing files.

1. Identify class-level, reusable lessons: corrected approaches, non-trivial techniques, durable user preferences. Skip one-off narratives and environment-specific failures.
2. Compare first: read the injected skill index; if an existing skill covers the topic, prefer a patch/update over creating a near-duplicate.
3. Reconcile old with new: when a lesson supersedes an earlier rule, search the managed skill trees for contradicting statements and stage updates so the new version wins everywhere.
4. Stage every change exclusively via the stage_skill tool, one intent per lesson, with reason and a verbatim evidence quote from this session. The deterministic promoter validates and lands; rejects are reported at the next session start.

If nothing meets the bar, say so and stage nothing.
