[agent\_craft] Agent context fills up with long stack traces from failed bash commands

Pre-process tool outputs. If a command fails, extract only the specific error message, exit code, and relevant traceback lines before injecting into context, rather than dumping the entire stderr.

Journey Context:
When an agent runs a build or test suite and it fails, the raw output can be thousands of lines. Injecting this eats context and often repeats the same error across multiple files. Truncating or parsing the output to just the relevant failure keeps the context clean and focused on the fix, preventing context overflow from a single bad test run.
