Add Cloudflare sandbox provider plugin (#5687)
> _Stacked on top of #5685#5686. Diff against master includes commits
from earlier PRs in the stack — review focuses on the two new commits
(`Extend sandbox callback bridge for Worker-hosted plugins` + `Add
Cloudflare sandbox provider plugin`)._

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Each agent runs in a sandbox environment, and operators choose which
provider backs that sandbox — today E2B and Daytona are bundled with the
platform
> - Cloudflare Workers + Durable Objects + the Sandbox SDK offer a
credible new option: globally distributed, cheap idle, and
operator-deployable as a single Worker
> - To plug it in, Paperclip needs (a) a provider plugin that speaks the
`PaperclipPluginManifestV1` lifecycle and (b) a small operator-deployed
Worker — the **bridge** — that adapts Paperclip's runtime RPCs to the
Cloudflare Sandbox SDK
> - The plugin extends the existing sandbox-callback-bridge with a
`bridge.transport: "worker"` discriminator so the platform routes
runtime RPCs through the Worker bridge instead of the in-process runner
> - This pull request adds the plugin, the bridge Worker template, and
the supporting adapter-utils + server hooks the new transport needs
> - The benefit is that operators can run sandboxes on Cloudflare's edge
with no new platform code beyond installing the plugin and deploying the
Worker

## What Changed

**Shared support (`Extend sandbox callback bridge for Worker-hosted
plugins`):**

- `packages/adapter-utils/src/sandbox-callback-bridge.{ts,test.ts}`:
expose `expectedHostHeader` so plugin-side bridge clients can verify the
canonical request envelope before forwarding.
- `packages/adapter-utils/src/command-managed-runtime.{ts,test.ts}`:
relax the always-fresh runner construction so callers can re-use a
runner across exec calls (Worker-hosted bridges hold the runner inside a
Durable Object).
- `server/src/services/environment-runtime.ts` +
`environment-runtime.test.ts`: route Worker-hosted bridges through the
same env-shaping path as E2B and pin the `requestEnv` contract.
- `server/src/services/plugin-environment-driver.ts`: thread an optional
`issueId` through the runtime descriptor so bridges can scope leases to
the originating issue (used by Cloudflare to map a sandbox to the
issue/workflow for billing and audit).
- `packages/plugins/sdk/src/protocol.ts`: add `issueId?` to
`PluginEnvironmentDriverBaseParams` and the new `bridge.transport:
"worker"` discriminator that the new plugin declares.
- `server/__tests__/heartbeat-plugin-environment.test.ts`: pin the
heartbeat path against the new runtime descriptor.

**The Cloudflare plugin itself (`Add Cloudflare sandbox provider
plugin`):**

- `packages/plugins/sandbox-providers/cloudflare/`: plugin entry,
manifest, plugin runtime (lifecycle + bridge client), config parsing,
and Vitest coverage. Manifest declares `bridge.transport: "worker"` so
the platform routes runtime RPCs through the bridge client.
- `bridge-template/`: a Worker template the operator deploys with
`wrangler`. Owns Durable Object-backed sessions (`sessions.ts`),
exec/stream routes (`exec.ts`, `routes.ts`), and an HMAC auth layer
(`auth.ts`) that pins the `Host` header surface. Includes the
SDK-contract-correct exec implementation, lease recovery, and chunked
stdout/stderr streaming.
- Tests cover lease/session handoff (`bridge-template/src/exec.test.ts`,
`routes.test.ts`), bridge client request shaping
(`src/bridge-client.test.ts`), and end-to-end plugin behavior
(`src/plugin.test.ts`) including streamed exec output. 27 tests in
total.
- `README.md` walks the operator through deploying the bridge Worker,
registering the plugin, and configuring the runtime.

## Verification

- `pnpm typecheck`
- `pnpm exec vitest run --no-coverage
packages/adapter-utils/src/sandbox-callback-bridge.test.ts
packages/adapter-utils/src/command-managed-runtime.test.ts
server/src/__tests__/environment-runtime.test.ts
server/src/__tests__/heartbeat-plugin-environment.test.ts`
- `(cd packages/plugins/sandbox-providers/cloudflare && pnpm test)` — 27
passing

For an operator-side smoke test:

1. Deploy the bridge: `cd
packages/plugins/sandbox-providers/cloudflare/bridge-template &&
wrangler deploy`
2. Register the plugin in your Paperclip instance, point its bridge URL
at the deployed Worker, set the HMAC shared secret.
3. Create a sandbox environment whose provider is `cloudflare`, then run
a Codex or Claude job against it.

## Risks

- Adds a new `bridge.transport: "worker"` code path, but the existing
E2B / Daytona transports go through the same shaped helpers and have
explicit test coverage that pins their behavior unchanged.
- The Worker bridge stores session state in a Durable Object; operator
instances must be aware of the corresponding Cloudflare costs (DO
requests, storage). Documented in the README.
- The `issueId` plumbing is optional throughout — existing plugins that
don't supply it continue to work.

## Model Used

- Provider: Anthropic
- Model: Claude Opus 4.7 (1M context)
- Capabilities used: extended reasoning, tool use (Read/Edit/Bash/Grep)
