fix(visual): address PR #48 review comments

- sound-indicator-visual: D-069 → D-033/D-048 color reference, reconcile
  medium range S1 (3-8) vs S7 (3-20) contradiction, split dual values in
  quick-reference table
- entity-color-system: D-046 → D-015 for peripheral rendering, tighten
  cognitive delay wording, add accessibility ticket tracking note
- visual-grammar-v01: dialogue max-width corrected from ~70% to 640px
  per D-076
- the-friend-visual-treatment: D-063 citation title corrected
- tell-visual-expression: soften D-024 attribution (axis, not categories)
- environmental-text-standards: specify tile unit for terminal visibility
- monologue-display-spec: header updated to reflect Sprint 14 inclusion
- CHANGELOG: add entries for all 6 Sprint 14 design docs

 **Entity in fog (recognized):** If the character recognizes an entity in fog (their knowledge graph identifies them), the insert overlay (z-layer 6) can show a D-033 color glow + faint silhouette feature at ±0.5 tile approximate position. This is insert data, not visual data — the character knows where they were, not where they are.
 
-**Entity at periphery:** Per D-046 (three-reference lighting model), entities in the peripheral vision zone are rendered at reduced saturation and alpha. The `modulate.a` value is `Constants.PERIPHERAL_ALPHA` when `visibility == "Peripheral"`. This is already implemented in `entity_renderer.gd`. The D-033 color itself does not change — saturation reduction is handled via the visibility dimming, not a color override.

 **Simultaneous transitions:** Two entities changing relationship state in the same tick each get independent 0.5s tweens. There is no synchronization between entity transitions. This is intentional.

 **Recommended for v0.1.2+:** Add a shape or pattern secondary signal to entity sprites — border dash pattern or icon badge — that persists independently of hue. E.g., Hostile gets a diamond border, PersonOfInterest gets a cross-hatch border, Unknown gets no border treatment. This would not require changing the D-033 colors (which have been visually designed and approved) but would layer a non-color signal on top.
