Make completed desktop tool rows read like useful activity labels instead of raw plumbing: terminal rows use a dispatch-style shell summarizer for agent wrappers, and read_file rows keep the action plus filename and requested line range.
The shell cleanup follows condensed-milk-pi's shape: split command compounds on real separators, strip pipe tails inside each segment, clean redirects/env prefixes, then classify setup/banner/status segments. Multi-command probes render as `first command + N commands`; the full command remains available in copy/detail.
Read rows now render as `Read package.json` or `Read main.ts L25-34`, using requested positive offset/limit and returned line numbers only as fallback for negative/unknown offsets.
