- Game.java: add 'platform' field ('dos'/'windows') + 'isPlayable' helper
- UploadResource.java: detect EXE type by reading PE/NE header during upload
- GameResource.java: allow PATCH to update platform
- GameCard.svelte: show 🪟 Win badge for Windows games (blue style)
- GameDetail.svelte: show platform badge, disable Play for Windows with
'Unplayable' button; add platform dropdown to edit form
- Play.svelte: show blocking overlay for Windows games with 'Try anyway'
option for users who want to attempt it
- Fix flattenSingleDir: flatten when exactly 1 root directory exists,
even if other metadata files (file_id.diz, *.nfo) are present at root
- Fix buildDosboxConf/buildJsdosJson: add 'cd <dir>' before executable
when it lives in a subdirectory, since DOS treats '/' as switch char
(previously 'mastori2/ORION2.EXE' was parsed as command 'mastori2'
with switch '/ORION2.EXE')
- Remove SockdriveResource.java entirely
- Remove bundleType field from Game.java (was 'standard'/'sockdrive')
