/status

Generate a comprehensive status report for a research project, combining structure stats, validation score, and Git telemetry.

## Goal
Produce `/project-management:status` output so the user can see readiness at a glance.

## Preparation
1. Ask for `root` path (default current).
2. Determine whether to include Git data (`include_git`, default true) and per-directory file stats (`include_file_stats`, default true).

## Execution
1. Confirm project exists. Collect `project_name=$(basename "$root")` and `last_modified` via `stat -f "%Sm"`.
2. Traverse directory tree (skip hidden) using `find` or `python - <<'PY' ...` to compute:
   - Total directory count
   - Total file count
   - Total size in MB (rounded to 0.1)
