Jan Nedbal 759b31d390 docs: record prior art survey and switch to velopack for self-update ...

After a survey of existing Metin2 launchers, general-purpose
auto-updaters, and adjacent open-source game launchers, update the
design to:

- drop the hand-rolled rename-before-replace self-update path
- use Velopack for launcher self-update (MIT, modern successor to
  Squirrel.Windows, handles atomic replace, delta, Authenticode, AV
  friendliness out of the box)
- keep the custom asset patcher for the 4 GB game payload, which
  Velopack is not designed for
- reference runelite/launcher as the architectural template
- name Sparkle 2 and wowemulation-dev/wow-patcher as Ed25519 prior art

No Metin2 community launcher is worth forking; the ceiling of
published prior art is 'file list + sha256 + HTTP GET' and this design
is already above it. Greenfield confirmed.
