[deep-report] Fix Daily Community Attribution Updater: update hard-pinned model to a supported Copilot model #28297

Description

The Daily Community Attribution Updater workflow fails immediately with 400 The requested model is not supported — the workflow has a hard-pinned model name that is no longer available on the current Copilot subscription tier. This is a recurring, daily failure that prevents community attribution from being updated. The same pattern is seen in GitHub Remote MCP Authentication Test (#27965) which is pinned to gpt-5.1-codex-mini.

Error observed (run §24885748725):

400 The requested model is not supported

Expected Impact

Restores daily community attribution updates. This is a quick frontmatter change. Identified as P1 in the Workflow Health Dashboard (2026-04-24).

Suggested Agent

An agent should inspect the workflow's frontmatter to find the model: or engine config field, identify an available and supported Copilot model, and update the workflow markdown. Should also audit whether other workflows have the same stale model pin to prevent recurrence.

Estimated Effort

Fast (< 30 min) — single frontmatter field update.
