quiet-run

When the user asks to run a verbose command quietly, run:

bash scripts/quiet-run.sh <label> -- <command...>

Wraps any verbose command so it doesn't spam the session — prints one line with
exit status, duration, and log path (/tmp/quiet-run-<label>-<ts>-<pid>.log).
<label> is a short slug for log naming; everything after -- is the command.
Grep the log if more detail is needed. See .claude/commands/quiet-run.md.

A background quiet-run is a live child of your session: count it (and any tail -f
or Monitor on its log) as a live child before closing or wrapping, not just
Agent-tool subagents. Killing it with TERM/INT/HUP reaps the whole command tree
when its stdin is not a terminal (every agent/CI run); with a tty on stdin it keeps
the foreground shape so the command can read the tty. SIGKILL cannot be trapped,
and a quiet-run started as a non-interactive & job inherits SIGINT ignored, so
INT is not reaped there (TERM/HUP still are).
