docs(readme): add deprecation banner pointing to Comfy-Org/Comfy-Desktop

[deepme987]

Adds a GitHub-alert banner at the very top of the README pointing visitors to the rewrite at Comfy-Org/Comfy-Desktop.

• New downloads: dl.comfy.org
• Existing 0.9.x users: in-app update to the new version as we roll out
• New issues / PRs / discussions: route to the new repo

The rest of the README is kept as historical reference — no content removed.

9-line addition.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Soften the in-app update guarantee to match actual updater behavior.

Line 7 currently guarantees automatic migration for all 0.9.x users, but updater behavior depends on user settings (Comfy-Desktop.AutoUpdate). Please make this conditional.

Suggested wording

-> - **Existing 0.9.x users:** your app will receive an in-app update to the new version as we roll out — no action needed.
+> - **Existing 0.9.x users:** if auto-update is enabled, your app should receive an in-app update to the new version as rollout progresses.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
