When the LLM API returns a context overflow error, trigger compaction instead of killing the session. Previously the catch block had a TODO comment and fell through to a fatal error (return 'stop'). Now: sets needsCompaction = true and breaks to post-catch cleanup, which returns 'compact'. The prompt loop then creates a compaction task, generating a summary and allowing the session to continue.

The following comment was made by an LLM, it may be inaccurate: Based on my search, I found one potentially related PR: Related PR:
Why it's related: Both PRs implement the same recovery mechanism (triggering auto-compaction when errors occur) to allow sessions to continue instead of failing. They follow the same pattern of setting a flag and initiating compaction. However, PR #14826 (the current PR) is not a duplicate — it addresses a different error type (ContextOverflowError from LLM directly) with its own distinct implementation. The related PR #14707 handles HTTP 413 errors. |

Closes #14824
Type of change
What does this PR do?
When the LLM returns ContextOverflowError, the processor now sets
needsCompaction = trueand breaks to post-catch cleanup, which returns "compact". The prompt loop then creates a compaction task (prune + summarize), allowing the session to continue with reduced context.Previously the catch block had
// TODO: Handle context overflow errorwhich did nothing — the error fell through to kill the session.How did you verify your code works?
