Replace all fatih/color usages with internal/ui package that provides:
- Semantic color tokens (Pass, Warn, Fail, Accent, Muted)
- Adaptive light/dark mode support via Lipgloss AdaptiveColor
- Ayu theme colors for consistent, accessible output
- Tufte-inspired data-ink ratio principles
Files migrated: 35 command files in cmd/bd/
Add docs/ui-philosophy.md documenting:
- Semantic token usage guidelines
- Light/dark terminal optimization rationale
- Tufte and perceptual UI/UX theory application
- When to use (and not use) color in CLI output
- Add `bd molecule list` to list template molecules
- Add `bd molecule show` to show molecule details
- Add `bd molecule instantiate` to create work items from templates
- Exclude templates from `bd list` by default (use --include-templates)
- Reject mutations (update/close/delete) to template issues
- Add IncludeTemplates to RPC ListArgs for daemon mode
Templates are marked with is_template=true and are read-only.
Use `bd molecule instantiate` to create editable work items.
