Two cleanup follow-ups that the parallel sessions which extracted these
modules left behind, surfaced by the route-drift test added in 6d193a9fa:
who — `chore: extract who module into standalone repo` (a3eedfc87) +
follow-up cleanup (f076d9345) removed `lib/modules/who/` and the
workbench `registerApp({ id: 'who' })` block, but the broken `/who/+page`
and `/who/play/[gameId]/+page` routes still imported the deleted module
and the MANA_APPS entry, APP_ICONS icon, categories.ts mapping and
help-content block were still in place. Drop all five.
kontext — `feat(notes): isSpaceContext flag replaces kontext module
(Option B)` (8fbdc6db7) replaced the kontext module with a per-note
`isSpaceContext` flag in the notes module. The MANA_APPS entry I added
in 6d193a9fa and the matching APP_ICONS entry are now both stale —
there is no `kontext` route, no module, no registerApp. Drop them.
Verification: `registry.spec.ts` 4/4 green, `svelte-check src/lib`
0 errors / 5 warnings (pre-existing in other files).
