promote: test → main (POST /api/sandbox + GET /api/sandbox/status)

[sweetmantech]

Promotes the just-landed sandbox routes from test to main.

What lands on main

• feat(sandbox): port POST /api/sandbox + GET /api/sandbox/status from open-agents (feat(sandbox): port POST /api/sandbox + GET /api/sandbox/status from open-agents #522, squash-merged into test as 42c701c0)
• Includes the bug fix for the loading-state UX (hasRuntimeSandboxState distinguishes type-stub from real runtime)
• Includes Tier 1 correctness fixes: GitHub URL validation, GITHUB_TOKEN plumbing, snapshot field clearing on fresh provision
• Drops the branch / isNewBranch request fields per docs PR docs(sandbox): drop branch + isNewBranch from POST /api/sandbox docs#194 (already merged on main)

Verification

• All CI checks green on feat(sandbox): port POST /api/sandbox + GET /api/sandbox/status from open-agents #522
• Smoke-tested twice on the preview deployment (both passes documented in the PR comments)

Summary by cubic

Promotes the sandbox API from test to main: POST /api/sandbox provisions or resumes a session-bound sandbox, and GET /api/sandbox/status reports lifecycle to power the chat “loading sandbox…” UX.

• New Features

  • Added POST /api/sandbox: validates GitHub repo URL, authenticates, derives deterministic sandboxName from sessionId for idempotent resume, persists sandbox_state/lifecycle, clears stale snapshot fields, and returns { createdAt, timeout, currentBranch, mode, timing }. Uses a 30m default timeout, port 3000, and forwards GITHUB_TOKEN when set for private repos.
  • Added GET /api/sandbox/status: DB-only; returns { status, hasSnapshot, lifecycleVersion, lifecycle }. Reports active only when runtime metadata exists and the sandbox isn’t expired (10s buffer).

• Bug Fixes

  • Fixed loading-state regression by treating the type-only stub { type: "vercel" } as no_sandbox until a real sandboxName is present.
  • Return 400 for invalid GitHub URLs to avoid confusing provider errors.
  • Dropped branch and isNewBranch from POST /api/sandbox; currentBranch now reflects the resolved sandbox state (per docs docs(sandbox): drop branch + isNewBranch from POST /api/sandbox docs#194).
