feat(web): persona pane shows the CANONICAL affect->NL Worldtree injects (v0.19.5)

The pane now renders the LITERAL mood word + relationship directive Worldtree
context-injects into the agent — adopted from Worldtree's canon, not invented:

- canonMood(pad) mirrors Worldtree describe_pad (valence×arousal grid, ±0.3 bands);
  for sindra's PAD the canonical render is "neutral" — an invented octant vocab
  would have said "faintly excited" and MISLED. Adopting canonical is the point.
- canonDirective(rel) mirrors render_d2_canonical byte-exact: "...warmth is clear
  warm regard; ability trust is strong; ...; speak with direct warmth; ..." — the
  exact stance instruction the agent receives (which makes the WAD "stranger"
  relation_context read even more incoherent, as flagged to worldtree-dev).
- Both VERIFIED byte-exact against Worldtree's OWN renderer on the live snapshot.
- Canon vendored (docs/vendor/worldtree-persona-canon/) + drift-pinned in
  .corviduo-canonicals.toml (canonical_drift green); flat browser form
  (static/persona_render_canon.json) regenerated by scripts/build_persona_canon.py
  via Worldtree's authoritative loader. Reference-impl posture: adopt canonical.
- Fail-open (canon absent -> lines omit); INV-004 esc() preserved.

JS syntax clean. Refresh + drive turns to see the canonical NL under mood + each
relation.
