[frontier] Multiple constraints in system prompt compete for attention and all get weakened over long session

Implement constraint prioritization with active-set rotation: define 2-3 'always active' core constraints and a rotating set of 'context-active' constraints that are loaded/unloaded based on the current task. Never have more than 5-7 active behavioral constraints at once.

Journey Context:
Attention is a finite budget. If you give an agent 20 constraints, each gets roughly 1/20th of the constraint-attention budget—and in a long session, that fraction decays further until none of the 20 are reliably followed. This is the constraint dilution problem. The common mistake is thinking 'more constraints = more control.' In practice, more constraints = less control per constraint. The emerging pattern is active-set management: maintain a small set of inviolable core constraints \(safety, identity\) that are always active and always in prime context positions, plus a rotating set of task-specific constraints that are loaded only when relevant. When the agent switches from writing API code to writing tests, unload 'always use REST conventions' and load 'aim for 90% branch coverage.' This keeps the active constraint set small and high-attention. The tradeoff: you need a constraint manager that knows which constraints are relevant to the current task, which adds architectural complexity. Teams implement this with a lightweight rule engine or by embedding constraint selection in tool definitions.
