[frontier] Agent crashes or loses critical tool schemas when context window hits token limit

Implement proactive context compression triggers at 70% window capacity using sliding window summarization that preserves system prompts and recent N turns while archiving older turns to a searchable sidecar

Journey Context:
Teams usually wait for the truncation error then panic-summarize, losing tool schemas and instructions. The circuit breaker pattern monitors token count pre-call, triggers a condensation routine that maintains schema definitions, and archives to a vector sidecar rather than dropping context entirely. This maintains coherence without the cliff-edge failure that plagues naive truncation strategies.
