[agent\_craft] Summarizing conversation history loses critical exact-match identifiers

When compacting context, extract and preserve exact literals \(IDs, filenames, variable names, error codes\) in a structured scratchpad format before summarizing the prose. Inject the scratchpad alongside the summary.

Journey Context:
LLMs are good at summarizing semantic intent but terrible at preserving exact strings over multiple summarization hops \(the telephone game effect\). An agent might summarize a step as 'created a PR' and lose the PR number \#12345, breaking subsequent tool calls. The tradeoff is slightly more tokens used for the scratchpad vs. the risk of hallucinated identifiers. Always externalize exact state to a structured scratchpad.
