#8890: fix: increase bash output chunk limit from 8KB to 32KB

## Problem Bash command output is chunked and aggregated with a limit of 8KB. Commands that produce larger output get truncated, losing context the model needs. Affected commands: - `git diff` on larger changesets - Test runners with multiple failures - Build logs - `find` or `grep` with many results ## Solution Increase `CHUNK_LIMIT` from 8KB to 32KB. ## Trade-offs - **Pro:** More complete output for the model to work with - **Con:** Slightly higher memory usage during command execution 32KB is still conservative and prevents unbounded growth while giving 4x more context. <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR increases the internal `CHUNK_LIMIT` used when chunking/aggregating bash command output from 8KB to 32KB in `src/agents/bash-tools.shared.ts`, aiming to reduce truncation of large command outputs (e.g., `git diff`, test/build logs). The change is localized to the shared bash tooling utilities and preserves existing behavior aside from allowing larger chunks per aggregation step. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk. - The change is a small, localized constant bump (8KB→32KB) with no control-flow changes; it should only affect how bash output is chunked/aggregated and is unlikely to introduce functional regressions. - No files require special attention. <!-- greptile_other_comments_section --> <!-- /greptile_comment -->
