- Add TypeCustomizePopover component with color swatches (6 accent colors)
and icon grid (35 curated Phosphor icons)
- Add right-click context menu on sidebar section group headers with
"Customize icon & color…" option
- Sidebar renders custom icons/colors from type entry frontmatter
- NoteList uses custom icons/colors for type badges and pinned cards
- Wire up onCustomizeType in App.tsx to update type frontmatter
- Add updateEntry to useVaultLoader for instant in-memory updates
- Add --accent-orange-light CSS variable
- typeColors utility now accepts optional custom color key overrides
Product decision: Built-in types can also be customized (override their
defaults), not just custom types. The picker is a simple popover that
appears after right-click → "Customize icon & color…".
