v5.5.0

Uploads that can't fit are now refused before they start, big folders
finish, and you can edit a mounted game image in place.

• "It won't fit" is said up front, not four hours in. The PS5 holds
  back a large chunk of internal storage that the free-space number never
  shows, so an upload could pass every check, run for seventeen minutes,
  and die at 53% with a connection error that never mentioned the disk.
  Uploads are now checked against the space actually usable, on both the
  app and the console, and the destination picker shows usable space
  instead of free space.
• If it does run out mid-upload, it says so. That failure used to
  surface as six identical "connection forcibly closed" messages. Now it
  names the drive, the numbers, and stops retrying something that cannot
  succeed.
• Folders with thousands of small files upload again. Anything over
  about 7,000 small files used to fail with an unreadable socket error
  after all the data had already arrived. A 20,000-file folder now
  completes.
• Edit a mounted disk image in place. Mount an .exfat read-write and
  the File Browser becomes an image editor: Add files copies files in
  from your computer, and Replace overwrites one file keeping its name.
  This is what lets you drop in DLC, swap assets, or apply a backport patch
  when a game ships as an image instead of a folder. Edits are permanent
  and there is no undo — the app now says so before you start.
• The sidebar is yours. It used to assume five screens mattered to
  everyone. Now only Home is pinned, and you star whatever you actually use
  from More.
• Firmware 12 installs stop pretending. The last-resort installer path
  could report success after copying nothing at all. It is gone from the
  automatic sequence; the app keeps your staged package and explains the
  real error instead.
• Translation fixes. "From" and "To" in the file move screens had been
  translated as the email senses — German read "Mr.", Spanish "born in",
  Japanese "start date". Several messages also showed raw \n and \"
  instead of line breaks and quotes.
• The sidebar shows which version you are running, so a bug report can
  say so without hunting through About.
