Show what each background monitor and command is running in the waiting strip

[saphid]

Problem

When a thread has settled but is still waiting on background work, the composer strip says something like "Waiting on 2 monitors" and lists their names. Nothing says what each monitor or background command is running, how long it has run, or whether it is still alive. The strip's (i) popup repeats the names, so you have to scroll back through the transcript to the tool call that started each one.

Proposed direction

Keep it small and read-only:

• Add optional command and startedAt fields to the pending background task roster entry. Older clients ignore them.
• Claude adapter: record the command and start time from the Monitor or run_in_background Bash call that started the task. Shared turn-item path: do the same for Codex and Grok. Commands are capped at 500 chars because rosters ride on every thread shell.
• Web: the strip's (i) popup lists each item with its status ("Monitor · running 2m") and its command. Mobile: tapping the waiting pill shows the same details.

There is no live output tailing and no new terminal surface. The popup just says what is running and for how long.

Before / after, from a real Claude turn running two Monitors:

I have an implementation with tests and evidence. I'll link it below as a PR marked "approval pending". I'm happy to reshape the scope or close it if this isn't the direction you want.

Thanks — open PR #15585 looks like the implementation for this idea (waiting-strip roster command / startedAt, Claude/Codex/Grok adapters, web (i) popup and mobile waiting-pill details). Linking it here so reviewers can find the evidence and discussion in one place.
