ReKHCoM Linux startup recovery test

Complete test archive v2.2.5-test459-startup.2, for issue459.

1. Extract into a NEW folder. Keep your working game and saves unchanged.
2. Put your own ROM in roms/.
3. Add this folder's ReKHCoM.sh to Steam, using your usual native command.
   For this test, remove --safe-startup from that command so Auto is tried.
   From a terminal: ./ReKHCoM.sh --auto
4. Give the first attempt up to 35 seconds. If native64 stalls before entering
   the game, Auto should continue through compatible32 software automatically.
5. Tell us whether the title appears, how long it took and whether HD text works.
   Attach ReKHCoM.log and kh_com.log from THIS new folder.

If it still does not start, --safe-startup remains available. Never delete the
working installation, your ROM or original saves. No new HD media import is
needed for the font/startup test. Fonts are included.

This is a targeted recovery test, not stable2.3 or a complete build of all latest
features. Game cores/internal version remain2.2.5 and preserve the prior HD-font
test; only native64 host, wrapper and these notes were replaced. SOURCE.json
records both provenances. The native64 GPU route stays the first attempt; only
timeout recovery uses software for that session, without saving that choice.
No timeout/relaunch is allowed after a game session enters.

The physical X11/Steam cause still needs confirmation. Local checks use an
isolated Debian snapshot and injected failures, not SteamOS hardware. Resolution,
codec, imported content and audio quality are unchanged. Proprietary ROMs/assets,
personal saves and private logs are not included.
