- Filegram can now send anonymous usage statistics: the app version, the
operating system and which features get used. File names, paths and folder
contents never leave the machine, counts and sizes are reported as ranges,
and the chart button on the start screen turns reporting off at any time.
See PRIVACY.md in the repository for the full list.

- Switched the Windows package to an Inno Setup installer. Filegram now lands
in the Start Menu, registers an App Paths entry, and appears in Apps &
Features, so it is reachable from Windows Search and uninstalls cleanly.

- Windows binaries now statically link the MSVC C runtime, so they run without
the Visual C++ Redistributable installed.
