v0.0.4

Added

• Uploads now carry each file's own modification date, so a photo taken in 2019 no
  longer arrives dated today. Servers that do not understand the date ignore it and
  keep dating uploads on arrival, as before.
• Chunked uploads from the desktop app declare the file's total size, letting the
  server reject an upload whose parts do not add up instead of publishing it as
  complete.

Fixed

• Sync daemon, desktop and mobile apps: uploading a large file no longer holds the
  whole file in memory. Content is streamed from disk, so a multi-gigabyte upload no
  longer risks exhausting memory — most noticeably on phones.
• macOS and iOS apps: a file that could not be read was silently skipped during
  upload. The upload reported success and the file was simply missing from the
  server. Read failures are now reported.
• Uploads declare their exact length, so a transfer that ends early fails instead of
  quietly storing a truncated file that looks complete.
• Desktop app: profiles created by pre-0.0.3 versions (no server stamp in the index)
  are now reset on first open — such an index may hold a poisoned merge of two
  servers' trees and previously kept showing ghost folders after re-pairing.
