Fix production build failure — every Vercel deployment has been erroring

[rprabhat]

Summary

Every Vercel deployment for at least the last 23+ hours has failed (Error status on prod and preview alike). Reproduced the failure locally with npm run build (Turbopack dev mode doesn't run the same checks a production build does — type-checking and full module resolution only happen at build time) and worked through the stack of failures one by one:

1. @crewcircle/knowledge unresolvable — its tsconfig.json had noEmit: true, so the package's own build script exited 0 while emitting nothing but a tsbuildinfo file. Root package.json never built it either. Added a prebuild script and fixed package.json's exports map, whose import conditions pointed at dist/index.mjs — a file the build never actually produced (real output goes to dist/esm/index.js).
2. Root tsconfig.json typechecked the entire monorepo — include: ["**/*.ts"] pulled every workspace package's source into the website's own typecheck, so an unrelated missing dependency in packages/observability failed the whole build. Excluded packages/* — each package already has its own tsconfig.json.
3. Github icon removed from lucide-react — the installed v1.26 dropped brand icons. Swapped for GitFork (the button's label text already says "GitHub").
4. InternalMemory.create() doesn't exist — admin/knowledge/page.tsx called a static factory method that was never part of the class. Fixed to new InternalMemory(...) + .initialize(), matching the actual class API (and its own test file).
5. DataTable<T> generic not inferred from JSX props — two admin tables passed untyped columns arrays; TypeScript fell back to the base constraint. Added explicit <DataTable<T>> type arguments and the index signatures T extends Record<string, unknown> requires.
6. Response vs NextResponse — 6 API routes catch the plain Response that requireAdmin() throws and return it directly, typed as NextResponse. Wrapped each in new NextResponse(...).
7. Stale app data — apps.ts and content.ts's FOOTER_LINKS had regressed to a wrong lineup (missing TaxFlowAI/LocalMate entirely, a fabricated "XeroAssist" entry that was never a real product) — traced via git log -S to a bad merge that clobbered a commit explicitly tagged "Build verified". Restored that verified data, cross-checked against the admin registry's actual provisioned projects (TaxFlowAI, LocalMate, CrewRoster, SmartGL, CardSnap, AuRate).

Test plan

• rm -rf .next && npm run build — completes cleanly, all 35 routes compiled/prerendered
• npx tsc --noEmit / npx eslint src --quiet — clean
• npm run start + curl smoke test: /, /admin, /admin/costs, /admin/observability, /admin/knowledge, /api/admin/health all return 200
• Vercel preview deployment for this PR
