v4.5.1

Added

• The navigation moved to a bar at the top: Downloads, Find and HUB as tabs,
  with the disk gauge and the active-download chip beside them. Prefer the old
  left sidebar? Settings > Appearance > "Classic side navigation" brings it
  back, nothing else changes.
• New Find page: Search and Discover merged into one. Browse the featured
  billboard and the poster shelves (movies, series, games, your list), or just
  start typing to search. Clearing the search puts you back where you were
  browsing. Navigation is now three tabs: Downloads, Find, HUB.
• "Mark as completed" moved to the main right-click menu (it shows up once the
  download finishes), and the seeding limits you set (ratio or time) now mark
  the torrent as completed automatically instead of leaving it paused forever.
• Setting a game executable shows a confirmation, and the game is playable
  right away, even while the torrent is still finishing other files.

Fixed

• Games: Play always responds. A finished game that was still seeding counted
  as "downloading", so Play silently did nothing. Launch failures now show a
  message and open the folder, executables that need admin rights get the UAC
  prompt on Windows, and .app bundles open correctly on macOS.
• Windows: mouse-wheel scrolling is fast now. Spinning the wheel used to crawl
  while dragging flew.
• Windows: the tray menu opens where you click, not in a corner it guessed.
• Boot protection: an interrupted update that leaves a mismatched engine DLL
  (our top crash in the wild) now shows a clear re-download dialog instead of
  crashing in a loop, and after any crashed start the next boot begins with a
  fresh engine state.
• Light theme: the game card button label is readable again, the HUB continue
  rails no longer render as black boxes, and the grid hover shadow no longer
  smudges on light backgrounds.
• Grid cards: a long status no longer overlaps the size column. Peers, files
  and trackers empty states are centered, and the peers table breathes at the
  top.

Changed

• The top bar leads with just the bat glyph (the full wordmark stays on the
  splash, About and the classic layout), and the grid selection ring is red.
