fix: ensure resume args precede image args

[cryptonerdcn]

Summary

Fixes argument ordering when resumeThread() is used with local_image. The SDK previously emitted CLI args with --image before resume <threadId>, which caused the Codex CLI to treat resume/UUID as image paths and start a new session. This PR moves resume <threadId> before any --image flags and adds a regression test.

Bug Report / Links

• OpenAI issue: Bug: resume + local_image starts a new session #10708
• Repro repo: https://github.com/cryptonerdcn/codex-resume-local-image-repro
• Repro issue (repo): Bug: resume + local_image starts a new session cryptonerdcn/codex-resume-local-image-repro#1

Repro (pre-fix)

1. Build SDK from source
2. Run resume + local_image
3. Args order: --image <path> resume <id>
4. Result: new session created (thread id changes)

Fix

Move resume <threadId> before --image in CodexExec.run and add a regression test to assert ordering.

Tests

• cd sdk/typescript && npm test
  • Failed: codex-rs/target/debug/codex missing (ENOENT)

Notes

• I can rerun tests in an environment with codex-rs built and report results.
