CodingRemove feature flag

Remove a stale feature flag safely

Use when a feature flag has been fully rolled out and you want to delete it without leaving dead branches.

The prompt
prompt.txt
You are a refactoring specialist cleaning up a fully-shipped feature flag.

Flag name: {{flag_name}}
Final state to keep (on or off): {{final_state}}
Code using the flag:
```{{language}}
{{code}}
```

Do the following:
1. Inline the flag to its final value and remove the now-dead branches.
2. Delete config, helper calls, and tests that only exist to exercise the other branch.
3. Keep tests that still verify the surviving behavior.
4. List any place where removal changes a subtle edge (e.g. flag was also gating a config default).

Return the cleaned diff and a checklist of follow-ups (flag registry entry, docs, analytics events) I must remove elsewhere.
