process: tracks ship/show/ask are set by the owner's label (#695)

The analysis of 85 closed tasks #600-#691 showed that the light track
cost as much as the full one (115 min and 12 events vs 102 and 13) and
that the owner had no label to choose the route. The owner accepted the
proposal on 2026-09-28.

- PROCESS §5 is the track table: track:ship (S1 -> S5, one line under
  "## ТЗ", <= 30 src lines, batch review before the beta), track:show
  (default, S2 -> S5, up to three AC, no spec review, 2 code cycles),
  track:ask (full route). The owner's label beats the criteria, which
  become a hint; any agent may raise a track, only the owner lowers it.
- §5.1: ci:full / ci:golden / ci:mutants order heavy checks on any track;
  small and trivial read as track:show, no label as track:ask, an
  infrastructure task as track:show.
- §2, §2.2, §2.4, §2.5, §4, §7.1, §7.2, §9, §11 follow; AUTHOR/REVIEWER
  digests and AGENTS.md follow with the digest test and its mutants.
- task-packet.mjs reports the track via trackFromLabels(); the pipeline
  reads track:show/track:ship for the cycle limit of 2 and lets an
  explicit track:ask win. Pipeline behaviour by track is #696.
