release(v4.0.1): strict-TS publishability fixes
4.0.0 shipped TypeScript source as published main/types, but several
files only compiled inside the monorepo. Consumer projects (Dispatch,
etc.) running their own strict tsc against our published source hit:

- @shade/key-transparency: 4 noUnusedLocals violations
  (IndexAbsenceProof, IndexInclusionProof, IndexProofWire, nodeHash)
- @shade/sdk: KT verifier callbacks returned Promise<unknown> instead
  of Promise<STHWire> / Promise<{ proof: string[] }>
- @shade/sdk: thumbnail.ts globalThis cast collided with consumer's
  lib.dom-supplied createImageBitmap signature
- @shade/files: cycle with @shade/sdk produced "this is not assignable
  to type 'Shade'" because hoisted node_modules layouts duplicated the
  Shade class. Broken by replacing `import type { Shade }` with a
  local structural ShadeBridge interface.
- @shade/storage-encrypted: KeyUsage (lib.dom) used under
  lib: ["ES2022"]
- @shade/transport-bridge: ReadableStreamDefaultReader<any> ↔
  <Uint8Array> mismatch
- @shade/keychain / @shade/dashboard / @shade/storage-encrypted
  tsconfig rootDir / include hygiene

Tooling: scripts/typecheck-all.ts runs `bunx tsc --noEmit` against
every workspace package's tsconfig and fails on any error. Wired into
publish:dry / publish:all and publish-shade.sh as a hard gate so this
class of bug cannot recur.

All 24 packages bumped to 4.0.1 in lockstep.

Migration: <ShadeFilesProvider> now requires an explicit `files` prop
(pass `shade.files`). Wire format unchanged.

@shade/transport-bridge

Transport-agnostic delivery for Shade: WS → SSE → long-poll, in priority order, behind a single IncomingMessage interface.

import {
  FallbackBridgeTransport,
  WsBridge,
  SseBridge,
  LongPollBridge,
} from '@shade/transport-bridge';

const auth = { crypto, signingPrivateKey, address: 'bob' };

const bridge = new FallbackBridgeTransport([
  new WsBridge({       baseUrl, auth }),
  new SseBridge({      baseUrl, auth }),
  new LongPollBridge({ baseUrl, auth }),
]);

await bridge.connect({
  onMessage: (msg) => {
    // msg: { from: string; bytes: Uint8Array; receivedAt: number; msgId?: string }
  },
});

console.log(bridge.activeKind); // "ws" | "sse" | "long-poll"

Pair with createBridgeRoutes in @shade/inbox-server to expose the matching /v1/bridge/{stream,poll,ws} endpoints. Full design + threat model in docs/transport.md.

What it solves

Browser extensions, strict corporate proxies, and edge runtimes routinely block long-lived WebSockets. Apps that already use the Shade inbox shouldn't have to write three custom delivery paths to handle the realistic mix of hostile networks they ship into. This package is the canonical answer.

Status

V3.7. Stable wire format, additive change to @shade/inbox-server. See CHANGELOG.
