lovstudio-cc-mv

Two modes in one tool:

Directory-level (default) — four things in one shot:

1. mv FROM TO on disk (fs.renameSync — instant, preserves everything)
2. Rewrites ~/.claude/projects/<slug>/*.jsonl session store — including every sub-directory slug
3. Rewrites ~/.claude/history.jsonl (prompt up-arrow recall)
4. Rewrites ~/.claude/sessions/*.json (running-session records)

Session-level (opt-in, via --session/--grep/--pick) — migrate a subset of chats:

1. Copies only the selected .jsonl files from FROM's slug dir into TO's
2. Rewrites each file's cwd from FROM → TO
3. Rewrites only the matching running-session records
4. Does not touch history.jsonl or fs mv (project itself isn't being moved)
5. Sub-dir slugs are ignored (root only by design)
