Report #3131

[agent\_craft] Failed tool calls and their error traces remain in context, confusing the LLM and causing it to repeat mistakes

Implement scrubbing or rollup of consecutive failed attempts into a single structured error summary, explicitly stating what was tried and why it failed, before retrying.

Journey Context:
An agent tries npm install, fails. Tries sudo npm install, fails. The context now has 2 huge stack traces. The LLM gets confused by the noise. Rolling up the traces into 'Attempted npm install: Error EACCES. Attempted with sudo: Error missing package.json' clears the token budget and focuses the LLM on the implication rather than the raw trace.
