This serves the agent handoff guide at /agent-handoff.md and makes that the canonical URL (sentry-agent-handoff). A .md path signals to agents that the guide is a plain markdown document to fetch, not a page to open with browser tools.

/agent-handoff/ keeps serving and claiming through the same view, renamed to sentry-agent-handoff-legacy, so prompts people have already copied still work.

The claim page builds its curl and Invoke-WebRequest commands from reverse("sentry-agent-handoff"). That means agents that land on either URL now POST their code to /agent-handoff.md.

controlsiloUrlPatterns.ts gets the new pattern because test_no_missing_urls requires it. #129973 and #130249 did the same when they added control-silo routes.

Follow-ups:

• A frontend PR, after this deploys, to point handoffPrompt.tsx and the preview link at /agent-handoff.md.
• Adding the .md route to the mocks in getsentry/sentry-for-ai-evals.
• Removing the legacy route once old prompts have aged out.

🚨 Warning: This pull request contains Frontend and Backend changes!

It's discouraged to make changes to Sentry's Frontend and Backend in a single pull request. The Frontend and Backend are not atomically deployed. If the changes are interdependent of each other, they must be separated into two pull requests and be made forward or backwards compatible, such that the Backend or Frontend can be safely deployed independently.
