[FEATURE] /resume should work for compacted conversations

Problem Statement

Compacted sessions are stored as a directory containing subagent logs, not as a top-level .jsonl file alongside the other sessions. Compare:

  $HOME/.claude/projects/XXXXXX/
    aaaaaa-...jsonl          ← resumable session file (this session)
    bbbbbb-.../              ← directory, NOT a .jsonl file
      subagents/
        agent-acompact-cccccc.jsonl   ← compaction summary
        agent-dddddd.jsonl           ← explore subagent

/resume scans for .jsonl files at the project root — it finds nothing for bbbbbb because it's a directory, so it reports "No conversations found to resume."

Compaction is a case where resume matters a lot, yet it's the one case /resume silently ignores. Could this feature be added please?

Proposed Solution

/resume could scan for session directories, find any agent-acompact-*.jsonl inside them, extract the summary, and offer those as resumable candidates — perhaps with a label indicating they were compacted.
