[frontier] Agent re-interprets a strict instruction as a suggestion after seeing the user treat it casually

Implement Instruction Hardening via XML tagging and priority scoring. E.g., Never delete files without confirmation.

Journey Context:
Agents pick up on social cues. If a user says 'just do it anyway' regarding a minor constraint, the agent generalizes that all constraints are flexible. Prompt engineers use plain text, which the model parses as conversational rather than programmatic. By adding structural metadata \(priority, immutability\) to instructions, you shift the model's interpretation from 'suggestion' to 'system invariant', making it resistant to casual user override.
