Both email providers now work in parallel on the same Worker:
- ForwardEmail: existing POST /api/inbound webhook (unchanged)
- Cloudflare Email Routing: native `email` handler using postal-mime
New files:
- src/lib/email-processor.ts shared business logic (feed lookup,
sender allowlist, KV storage) extracted from inbound.ts
- src/lib/cloudflare-email.ts Cloudflare `email` handler; parses
raw RFC 2822 email with postal-mime, delegates to processEmail()
- src/lib/email-processor.test.ts 9 unit tests
- src/lib/cloudflare-email.test.ts 5 integration tests
Also fixes pre-existing CORS 204 response: c.text("", 204) →
c.body(null, 204) to match Hono's EmptyStatusCode constraint.
To enable: configure Cloudflare Email Routing with a catch-all rule
`*@domain.com` pointing to this Worker.

- Add `typecheck` script (`tsc --noEmit`) to package.json
- Remove conflicting `declare global` from test/setup.ts (superseded
by @cloudflare/workers-types); use `globalThis as any` for test globals
and declare minimal `require` locally to avoid pulling in @types/node
- Cast `createMockEnv()` and `deleteRes.json()` results in admin.test.ts
to silence strict `unknown` / MockKV-vs-KVNamespace errors
