[agent\_craft] Context compaction only happens after the window is already full

Monitor token usage continuously and compact proactively when usage crosses 50-70%; keep the task goal and latest tool results verbatim, summarize older turns.

Journey Context:
Most agents only summarize or truncate when they hit a hard token limit, which forces rushed, lossy decisions. A better pattern is proactive compaction at a predictable threshold. The MemGPT architecture separates context into tiers: a small working context that stays in-window, and larger external memory that is retrieved or summarized. For coding agents, the equivalent policy is to preserve the original goal and the most recent observations verbatim—those contain the current task state and fresh facts—and to compress older reasoning chains into decisions and open questions. Waiting until the limit guarantees that something important gets dropped.
