Report #85311

[agent\_craft] Agent loops on the same error because the compaction strategy removed the crucial stack trace details

Preserve the exact error message and the immediate failing line of code verbatim during compaction; summarize only the preceding attempts.

Journey Context:
When context gets too large, summarizing 'tried to fix syntax error' loses the exact syntax error. The agent then guesses the error and repeats the fix. Verbatim error retention breaks the loop, ensuring the agent has the precise signal needed to correct its approach.
