release(v4.1.0): browser-friendly HTTP RPC for @shade/files
Default shade.files.client(peer) requires both peers to be mutually
addressable over HTTP — the response round-trips through
Shade.deliverControlEnvelope (POST to peer's /v1/transfer/control).
Browser tabs can't host an HTTP server, so they couldn't consume
@shade/files at all. Dispatch's filutforsker (admin-panel browser UI)
is the canonical use-case.

This release adds a parallel request-response transport: one POST per
RPC, encrypted envelope in the body, encrypted response in the same
HTTP response. No inbound channel needed on the client.

### New API

- shade.files.rpcRoute(opts?) — Hono app exposing POST /rpc.
- shade.files.httpClient(peer, opts) — request-response FileClient.
- FilesNamespace.serve(handler, { inlineOnly: true }) — skip streams-
  bridge (and its configureTransfers pre-condition); also skip
  channel-based dispatch so requests aren't double-dispatched.

### Limitations (v1)

Inline only (≤ 256 KiB). Streamed reads/writes throw clear errors
directing to shade.files.client(peer) on a server-to-server deploy.

### Tests

7 integration tests in tests/integration/http-rpc.test.ts covering
round-trip + negative cases (sender header, empty/garbage body,
maxBodyBytes, rpcRoute-without-serve).

### Symmetry

Mirrors @shade/server's shade-auth-middleware: encrypted envelope in
request body, decrypted via existing ratchet, response in same HTTP
roundtrip. No WebSocket, no SSE, no outbound from server.

Wire-compatible. Source-compatible. Lockstep bump to 4.1.0.

@shade/transport-webrtc

V3.11 — direct peer-to-peer chunk transport for Shade transfers via RTCDataChannel. Plugs into @shade/transfer's ITransferTransport contract and wires automatically into @shade/sdk via shade.configureWebRTC().

import { createShade } from '@shade/sdk';
import { nativeRtcFactory } from '@shade/transport-webrtc';

const shade = await createShade({ prekeyServer });
shade.configureWebRTC({ factory: nativeRtcFactory() });
shade.configureTransfers({ resolveBaseUrl });

await shade.upload({ to: 'bob', input: file });    // → P2P when NAT allows,
                                                    //   HTTP otherwise.

See docs/webrtc.md for the full guide: NAT-traversal realities, TURN config, glare resolution, wire format, diagnostics, and end-to-end test recipes.

What's inside

  • WebRtcConnection — one peer connection between two Shade endpoints, driving offer/answer/ICE through Shade's own ratchet.
  • WebRtcConnectionManager — per-peer pool with deterministic glare resolution.
  • WebRtcSignalingChannel — JSON signaling messages multiplexed over Shade.send / Shade.onMessage.
  • WebRtcTransferTransport — implements ITransferTransport over the managed DataChannel; ack-correlated by 16-byte requestId tokens.
  • MemoryRtcFactory — in-process WebRTC simulator for tests.
  • nativeRtcFactory() — adapter over globalThis.RTCPeerConnection (browsers / Deno / Cloudflare Workers).

Adapters

@shade/transport-webrtc ships only the standard-API adapter (nativeRtcFactory). For Bun / Node, wrap your library of choice behind the IRtcFactory interface — only createPeerConnection, createDataChannel, and standard addEventListener are required.
