[frontier] Unbounded context growth causes token limit crashes in multi-step agents

Implement explicit token budgeting with context window allocation per agent step and early truncation heuristics

Journey Context:
Agents often crash mid-task when cumulative context exceeds model limits \(128k-200k tokens\). Production systems now implement 'token accounting' where each step declares its budget, and the orchestrator proactively summarizes or checkpoints when thresholds approach. This includes 'prompt caching' strategies \(storing system prompts in cache to reduce token count\) and 'hierarchical summarization' where only salient facts progress to the next step, preventing catastrophic context overflow.
