Add network timeouts and more robust error handling across scrapers/hosts, improve logging concurrency, and refine download handling:
- Hosts/sources: add request timeouts (15s) and exception handling to buzzheavier, gofile, steamrip, uztracker and rutracker; use urllib.parse.quote for search queries and better parse error checks.
- GoFile: use Session with try/finally, create guest account with timeout, validate API responses and close session.
- Context menu: import DirectDownloadHandle and handle stopping direct downloads separately from libtorrent; simplify file deletion with single try/catch; improve logging on exceptions.
- GUI/search flow: move UI state changes (clear table, disable searchbar, hide empty results) into MainWindow._start_search and reduce duplicated UI changes in run_search.
- Main: remove duplicate is_running assignment.
- Libtorrent: snapshot seeded magnets in update loop to avoid concurrent access; minor indentation change in add_seed.
- State/logging: add _log_lock to AppState; protect state.log_buffer with lock in consoleLog and flush_log_buffer and fix flush semantics.
- Updater: replace busy-wait with QEventLoop/QTimer polling for DirectDownloadHandle progress, stop timer and quit loop on completion/error, and remove unnecessary sleeps.
These changes aim to make network operations more reliable, prevent UI freezes, avoid race conditions when logging, and handle direct vs libtorrent downloads more cleanly.
UI: remove trackertable from the Search tab and reorder widgets to correct layout. Tab helper: add QLayout directly instead of wrapping it in a temporary QWidget to avoid extra nesting. Search helper: clear the trackertable rows and reset state.posts when starting a new search to ensure fresh results. Minor: import check_space in main and simplify an unused loop variable in libtorrent_int for clarity/linting.
