Send session for review ($improve-convex-plugin)

Ships the current Codex session transcript to anteater's /review endpoint, which runs an AI post-mortem and returns concrete findings to improve the runbook / bootstrap / skills. The user's text after $improve-convex-plugin is an optional note about how the run went (pass it as --idea).

Run it (QB_HARNESS=codex tells the helper to read the Codex transcript):

curl -fsSL "https://basic-anteater-667.convex.site/send-transcript" \
  | QB_HARNESS=codex bash -s -- --idea "<the user's note, or the app idea>"

Read the output:

• REVIEW_DONE status=done → summarize for the user: overall outcome + summary, then the top findings by severity (each: title → target → suggestedFix), then the wins. Keep it about the system, never paste back secrets (the helper already redacts).
• REVIEW_PENDING → it was submitted; the review is still running. Tell the user it's queued (the printed /review/<id> can be re-checked).
• REVIEW_NO_TRANSCRIPT / REVIEW_TRANSCRIPT_TOO_SMALL → no Codex transcript found; tell the user.
• REVIEW_UPLOAD_FAILED → the endpoint was unreachable (network/sandbox) — report it.
