Route the knowledge-tree (tech/culture) screen off 26 inline Color()
literals onto the design-token system.
- Add color.tech.* (8 node-state bg/border) + color.unlockAccent.* (7
badge accents + dim) to design-tokens.json using exact-hex equivalents
of the prior literals — zero visual change for cards/badges by
construction.
- Regenerate ui_theme.tres via tools/build-ui-theme.py (--check clean).
- Remap detail-panel/text literals to existing background.panel /
border.panel / border.divider / text.* / accent.* tokens.
- const→var refactor seeded in _resolve_theme_colors() (ThemeAssets.color
isn't const-eval safe), called before _build_layout().
- Compact the indicator-badge spec block to a data-driven loop (identical
tooltip output, fixes max-line-length).
Verified on plum: JSON valid, theme --check clean, all 26 token refs
resolve, no stale const refs (incl. subclasses), gdlint clean except the
pre-existing max-file-lines (file predates this pass; engine/scenes/ is
not gdlint-gated). Apricot visual proof pending (no godot import on plum).
