[goose-edit done]

Files touched:
- `.claude/plugins/quacker-channel/src/acp_dispatch.rs`

Test/build output:
```
cargo test -p quacker-channel tail_lines
...
test acp_dispatch::tests::tail_lines_keeps_last_n ... ok
```

VERDICT: Renamed the `n` parameter to `max_lines` in `fn tail_lines` and updated its single use inside the function body. No other changes. Tests pass. Ready.
