fix(ci): record fatal sidecar startup probe stacks

[seonghobae]

Purpose

PR #1026 exact head 03bbd9b4e436723a4ad84688e871b3658367aeb5 failed Noema sidecar provisioning in run 36320408930, job 108641784937 on cwlab-s1-02. The offline HTTP boundary probe terminated with signal 11 (exit 139) before any model review. The current log contains the heredoc source but no crash stack, preventing attribution to interpreter/runtime versus a specific call.

Enable Python stdlib faulthandler only inside that fixed offline probe, before orchestrator imports. Fatal output contains stack locations and no frame locals or request bodies. The existing failing exit and all HTTP/body/tool-description assertions remain intact. This is diagnostic instrumentation, not a claim that the native crash is fixed.

Verification

• GITHUB_ACTIONS=true: sidecar contract suite, 30 passed.
• bash -n scripts/ci/contextual_orchestrator_review_sidecar.sh: passed.
• git diff --check: passed.

After central integration, run a fresh trusted same-head Noema dispatch and inspect any fatal stack. Do not count a missing model verdict as approval and do not bypass #1026.
