* api: run the perpetual loops in one Sanic-managed process The singleton background loops (file worker, downloads, switches, jobs, bulk tag, flag checks, update check) now run in a dedicated process that Sanic's Worker Manager owns: `run_perpetual_process` is registered with `app.manager.manage()` from `main_process_ready`. The manager guarantees a single instance and SIGTERMs it on shutdown. No server worker runs the loops, so the owner-pid / heartbeat / watchdog claim scheme is deleted rather than hardened. `perpetual_signal` keeps its name and is now a plain registrar. A new `per_worker_task` registrar covers loops every server worker must run for itself: syncing its log level (previously only the owner did, so the other workers never picked up level changes) and a health check that asks the manager to restart the perpetual process when it is FAILED (Sanic marks a dead managed process but does not restart it). Downloads are started as background tasks instead of Sanic signals; the perpetual process has no server, so no finalized signal router. The update check and the upgrade-check endpoint run git in a thread via `refresh_update_status`. /api/status lists the perpetual process next to the servers.

Shutdown: cancel_background_tasks / cancel_refresh_tasks gather with return_exceptions, so a cancelled child's CancelledError no longer aborts the shutdown that called them (the process exited 1 with a download in flight). Restart after a crash: reconcile_after_predecessor heals shared locks a dead process left held, fails RUNNING Jobs owned by a dead pid, clears processing_domains, renews pending Downloads, and resets the file-worker status before the loops start. N server workers issue one restart request per cooldown through a shared timestamp in shared_ctx. The log-level sync now also runs in the perpetual process. Manage() is registered through register_perpetual_process so it is testable; the entry point refuses to run with no loops registered (spawn). Tests exercise the real entry point in a forked process with a live background task under SIGINT and SIGTERM, Sanic's real WorkerManager marking a crashed managed process FAILED and reviving it on restart, Sanic's process naming and ProcessState enum, the listener registration, and the reconcile step.
