/**
 * cli-deactivate.ts
 *
 * Called by Claude Code's SessionStart[clear] hook after /clear.
 * Writes a session marker with projectId=null for the new session so the
 * statusline shows "no project" instead of the previously active project.
 *
 * Also deletes the per-process active-project file and clears statusline
 * cache files so the change takes effect immediately.
 *
 * Usage: hmem deactivate  (reads stdin JSON from Claude Code hook)
