chore(dev): chore: Update devcontainer prebuilt image reference

[gh-worker-campaigns-3e9aa4]

Prebuilt devcontainer image reference updated to reflect latest config.

This automation in driven by the workspaces-image-builder service and the github-devcontainer-prebuild service.

For workspaces on-call: If there are any unexpected behaviors with this automation, see the troubleshooting runbook.

Regression Detector (Agent Data Plane)

Run ID: bd81fd7b-8315-4159-b5d5-e6a896f591b5
Baseline: ff0b4409 · Comparison: 38f1cb08 · diff

Optimization Goals: ✅ No significant changes detected

Fine details of change detection per experiment (5)

Experiments configured erratic: true are tagged (ignored) and skipped when determining which experiments regressed or improved. Experiments which are detected as erratic at runtime are tagged (erratic) to flag that the run's sample dispersion was high, but their regression / improvement signal still counts.

Explanation

A change is flagged as a regression when |Δ mean %| > 5.00% in the regressing direction for its optimization goal AND SMP marks the experiment as a regression (is_regression: true). Improvements use the matching criteria for the improving direction. Experiments configured erratic: true (tagged (ignored)) are skipped outright; experiments detected as erratic at runtime (tagged (erratic)) still count, since that flag describes sample dispersion rather than directional certainty. The Δ mean % cell is colored accordingly: 🟢 = improvement, 🔴 = regression, ⚪ = neutral. Reduction in CPU or memory is an improvement; reduction in ingress throughput is a regression.
