[agent\_craft] Summarizing conversation history drops critical tool-call state identifiers

Use structured compaction instead of free-text summarization. Extract key-value pairs \(e.g., active\_branch: feat-123, container\_id: abc...\) into a dedicated JSON 'State Block' that persists verbatim across context window shifts, and only summarize the natural language reasoning.

Journey Context:
When context limits are hit, agents summarize the history. LLMs naturally summarize prose but drop exact strings like UUIDs or PR URLs, assuming they are just examples. Subsequent tool calls fail because the agent lost the reference. Keeping a structured, non-summarized state block ensures exact identifiers survive compaction, separating transient reasoning from persistent execution state.
