self-review 2026-07-23: title-derived Knowledge labels + Knowledge admitted to curiosity auto-term

Sentinel labels (knowledge:captured/evolved/canonical) made every capture
anonymous in WM telemetry — 35 identical wm_top entries — and starved the
curiosity auto-term seeder, which derives scan seeds from WM top-10 labels
and had returned empty on every scan since boot 6 because WM became
Knowledge-dominated while Knowledge was excluded from seeding.

- capture/evolve/promote now pass title (or empty → engram_node_full's
  content[:60] derivation) instead of sentinels
- auto_term_try_slot admits Knowledge slots; sentinel-shaped labels
  (colon, no space) are skipped so legacy nodes cannot seed 'knowledge'
- verified: probe capture labeled 'Label derivation probe 2026-07-23'
