Brooklyn Nicholson e0325cf769 feat(desktop): Capabilities foundation — shared utils, master-detail, editors, primitives
The reusable base the Capabilities rework sits on:
- lib/{text,time,format,json-format}: consolidate ~30 hand-rolled string/date/
  number/JSON helpers behind one set of tested utilities.
- master-detail scaffold (MasterDetail / ListColumn / DetailColumn / DetailPane /
  CapRow / ListStrip / ToolChip / ICON_BUTTON) + row-hover; tabs-as-data
  PageSearchShell; EmptyState + ErrorBanner; a shared LogTail terminal surface.
- framed CodeEditor + JsonDocumentEditor, wired into every in-app markdown/JSON
  edit surface (profile SOUL.md, memory nodes, right-click sidebar profile).
- shared React Query cache helper (writeCache) + per-profile-switch/ debounce hooks.

// THE compact-number formatter — every user-facing count/token figure goes
// through here. 999 → "999", 1000 → "1k", 1230 → "1.2k", 10000 → "10k",
// 1_500_000 → "1.5M". Do not hand-roll `/ 1000` display math elsewhere.
export function compactNumber(value: null | number | undefined): string {

const scaled = (v: number, suffix: string) => `${v.toFixed(1).replace(/\.0$/, '')}${suffix}`
// Thresholds sit just under the unit boundary so rounding can't produce
// "1000k" or "1000" — those promote to the next unit instead.
