[frontier] Context window overflow truncating critical system instructions

Implement explicit token budgeting with dynamic allocation between System, Memory, Tools, and Scratchpad based on task phase

Journey Context:
Most agents treat context as a FIFO queue or simple truncation, losing system prompts or recent critical data. Advanced implementations treat the context window as a managed resource budget \(e.g., 128k tokens = 100%\). Different task phases require different allocations: planning needs more scratchpad, execution needs more tool context, reflection needs more memory. Dynamic reallocation prevents overflow of critical sections by explicitly reserving headroom for system prompts and compressing or evicting lower-priority sections \(like old tool results\) first. This is distinct from simple truncation which is indiscriminate.
