Add CreateOS Sandbox provider

[pratikbin]

Why

Adds CreateOS Sandbox as a provider: createos() runs sandboxes on NodeOps' VM-based CreateOS platform via the official @nodeops-createos/sandbox SDK, giving agent workloads normalized files/commands/lifecycle/preview access through the same Sandbox SDK surface as the existing providers.

CreateOS currently ranks #2 of 21 providers on the independent ComputeSDK Sandbox Benchmark — Sequential TTI, composite score 99.5 — and #2 on the Dax benchmark (7/7 phases completed, 47.92s median total duration).

What changed

• add createos provider adapter (packages/sdk/src/providers/createos/index.ts), package export (@opencoredev/sandbox-sdk/createos), capability metadata, example, and unit + live test coverage
• map CreateosSandbox* error classes (auth, permission, not-found, timeout, rate-limit, validation, server, connection) onto normalized SandboxError codes, with timeout/rate-limit/server/connection marked retryable
• files.list/mkdir/remove/exists implemented over shell (ls -1apL, mkdir -p, rm -rf, test -e) since the underlying SDK only exposes upload/download
• run()/start() wrap commands in bash -c, injecting per-call cwd/env via shell export/cd prefixing; start() bridges the SDK's async-iterator stream into the SDK's process/output contract
• expose() lazily enables ingress on first call and returns the provider's preview URL
• snapshots are unsupported (unsupportedSnapshots("createos")); pause/resume/fork are reachable via sandbox.raw
• register createos in providerNames, metadata.ts, capabilities.ts, tsdown.config.ts, and package.json exports/dependencies (@nodeops-createos/sandbox as an optional peer, pinned ^0.7.1)

Testing

• bun install
• bun run lint — 0 warnings/errors
• bun run typecheck
• bun run build
• bun run test — 49 pass, 0 fail (includes 5 new createos unit tests mocking the SDK client); 26 skipped, including 9 createos live tests gated on CREATEOS_SANDBOX_API_KEY/CREATEOS_SANDBOX_BASE_URL
• npm pack --dry-run in packages/sdk

Notes

• Live validation (real CreateOS sandbox create/run/files/ports/pause-resume/fork) requires CREATEOS_SANDBOX_API_KEY + CREATEOS_SANDBOX_BASE_URL and was not run in this environment; the live suite skips cleanly without them.
• stdin is not available on exec, matching the underlying platform's runCommand API — process.write() throws unsupported.

Greptile Summary

Adds CreateOS as a supported sandbox provider.

• Implements normalized file, command, process, lifecycle, port, capability, metadata, and error-mapping behavior.
• Registers the provider’s package export, optional peer dependency, build entry point, example, and provider metadata.
• Adds mocked unit tests and credential-gated live coverage for CreateOS operations.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failures remain within the scope of the reviewed changes.

T-Rex Logs

What T-Rex did

• Validated the file-list normalization behavior by comparing results before and after adapter capture, noting a failure prior to capture and all tests passing after capture.
• Validated the module export path resolution by comparing results before and after export capture, noting Node reported ERR_PACKAGE_PATH_NOT_EXPORTED before capture and a successful import resolving to provider id createos with the expected unsupported capabilities after capture.
• Concluded that no executed behavior contradicted the PR.
