feat(skill-listing): add CA-SKL-002 aggregate listing-budget check

Syklus 2 of Fase 4 Items 2+3. Flags when the sum of active skill
descriptions exceeds the listing budget (~2% of context, CC 2.1.32).

Design (operator-confirmed "fact-first, 200k anchor"):
- low severity (estimate) vs medium for the verified 1,536-char cap
- each description counted up to the 1,536 cap (what actually loads in
  the listing) — avoids double-counting the tail CA-SKL-001 flags
- fires when sum > 2% x 200k = 4000 tok; evidence leads with the measured
  sum + a calibration note that the budget scales 5x on 1M-context models
- aggregate emitted after the per-skill loop so the common case reads
  001=cap, 002=aggregate (finding IDs are a sequential counter, not stable
  semantic IDs — tests match on title, never NNN)

Also:
- tailored humanizer static entry for the aggregate title
- fix latent HOME leak in posture-grade-stability.test.mjs: it spawned
  posture.mjs without hermeticEnv(), so a real ~/.claude leaked HOME-scoped
  SKL/COL findings into the baseline grade (Token Efficiency A->B). Now
  isolated like the 8 other CLI-spawning tests.
- docs sync: test count 868->875, scanner-internals, gap-matrix, plan status

Suite 875/875, no snapshot drift, self-audit clean.
