# Internal helper for rclaude — prints one tab-separated line per Claude
# project directory under ~/.claude/projects/, sorted by most recent first.
#
# Output columns:  <mtime_epoch>\t<cwd>\t<session_count>
#
# Used by `rclaude list` and `rclaude resume` to discover sessions that exist
# on disk but have no live tmux session attached. Run locally or invoked
# remotely via ssh.
