Fix incomplete game path updates in batocera.conf

[Copilot]

The random game selector was updating only 2 of 4 game path references in batocera.conf, causing the emulator to load incorrect games despite correct metadata being displayed.

Problem

batocera.conf contains 4 locations referencing the selected game:

• -rom parameter (actual file emulator loads)
• -systemname parameter (metadata/display)
• global.bootgame.path (global setting)
• System-specific settings: system["file.ext"].setting=value

Previous implementation only updated the last two, leaving -rom and game-specific settings pointing to stale games.

Changes

Extract and validate system context:

# Extract system name from boot command
system=$(grep "global.bootgame.cmd" /userdata/system/batocera.conf | grep -oP '\-system \K[^ ]+')

# Extract filename for game-specific settings
new_game_file=$(basename "$new_game")

Update all four locations:

# 1. Update -rom parameter
sed -i "s|\(-rom \)[^ ]*|\1${escaped_game}|" /userdata/system/batocera.conf

# 2. Update -systemname parameter
sed -i "s|\(-systemname \)[^ ]*|\1${escaped_game}|" /userdata/system/batocera.conf

# 3. Update global.bootgame.path
sed -i "s|^global\.bootgame\.path=.*|global.bootgame.path=${escaped_game}|" /userdata/system/batocera.conf

# 4. Update system-specific settings (e.g., mame["old.zip"].tdp → mame["new.zip"].tdp)
sed -i "s|^${escaped_system}\[\"[^\"]*\"\]|${escaped_system}[\"${escaped_filename}\"]|g" /userdata/system/batocera.conf

Add proper escaping:

• Escape sed special characters (&, \, /) in file paths
• Escape regex metacharacters (., [, *, ^, $) in system names
• Validate system extraction with graceful fallback

Example

Before:

global.bootgame.cmd=... -rom /roms/mame/19xx.zip ... -systemname /roms/mame/btimem.zip
global.bootgame.path=/roms/mame/btimem.zip
mame["1941.zip"].tdp=100.000000

After:

global.bootgame.cmd=... -rom /roms/mame/btimem.zip ... -systemname /roms/mame/btimem.zip
global.bootgame.path=/roms/mame/btimem.zip
mame["btimem.zip"].tdp=100.000000

after running random_game.sh:
system.cpu.governor=schedutil

global.bootgame.cmd=emulatorlauncher %CONTROLLERSCONFIG% -system mame -rom /userdata/roms/mame/19xx.zip -gameinfoxml /tmp/game.xml -systemname /userdata/roms/mame/galagamf.zip

It only changed the game.xml line</issue_description>
