Add controlled session‑only developer debug mode inside Creator Settings

Add an optional high‑risk developer debug mode at the bottom of Bedrock’s Creator Settings. It unlocks native hidden debug UI for add‑on creators to troubleshoot resource‑pack and behavior‑pack bugs. All features are built‑into retail client; no game file modification required.

Safeguards against accidental activation:

Button placed at Creator Settings bottom.

Warning popup: risk of instability, crashes and world corruption; no official support; users must follow Minecraft EULA.

1‑minute mandatory reading timer; inputs locked until finished.

Manual typed confirmation required, copy‑paste disabled.

Generate one‑time activation token link for user to paste and enable.

Final reminder: debug mode works only for current session, resets after game restart. Auto‑disabled in multiplayer / Realms; single‑player only.

Constraints:

‑ Debug states clear on game exit, no permanent config or save changes.

‑ Resource packs cannot edit this debug panel. It cannot alter vanilla Ore‑UI layouts or inject custom buttons into vanilla menus. Custom UI must use DDUI pop‑ups.

Reason:

Retail Bedrock lacks official debug tools for add‑on developers. Many creators modify client files to get debug access, violating the EULA. This optional official tool provides a compliant troubleshooting path. Safeguards lower misuse and invalid bug reports. Normal add‑on creation does not need this mode.
