Loop engine for AI agents — routines over REST, MCP, and a built-in web UI

/// Migrate legacy UUID-named routine directories to the current slug-based layout.
///
/// Early daemon versions stored each routine under `{routines_dir}/{id}/` (the UUID). The current
/// layout uses `{routines_dir}/{slugify(title)}/`. After an upgrade the legacy dir still holds the
/// real `routine.toml` + `prompts/prompt.compiled.local.md`, while the crontab sync creates a *fresh*
/// slug dir containing only `run.sh` — so the cron `cp prompt.compiled.local.md` reads an empty dir
/// and the agent launches task-less.
///
/// For every on-disk routine whose directory name does not already equal its slug, this re-persists
/// it into the slug dir (preserving any `run.sh` already there) and removes the stale legacy dir.
/// Idempotent: routines already in their slug dir are skipped. Call once at startup before
/// `load_store` so the in-memory store reflects the canonical layout.
