feat: read ES-DE MAME search paths

ES-DE starts standalone MAME with -rompath %GAMEDIR%\;%ROMPATH%/<system> in 78 live commands across 54 systems (resources/systems/linux/ es_systems.xml at retrodeck-main-20261103-162710, 15e1b236; two more are commented out). The command line outranks mame.ini, so RetroDECK's MAME reads its sets in the roms folder each command names and in no BIOS folder. The ES-DE rom folders parser now records, per folder, the folders a standalone command passes as its ROM search path and the machines it starts, or that the game is the machine (%BASENAME%). Rescraped at the pinned revisions: retrodeck, emudeck and emudeck-windows gain these records and nothing else. A command reads the sets its machines load: the machine's own set, the BIOS sets on its romof chain and the device sets with ROMs it instantiates, from games/arcade/mame.json (mame0289 -listxml). That index now also lists the game and device sets of each driver source file, so a %BASENAME% folder reads for its board: neogeo and stv by their BIOS root, cps1-3 and model2 by source file, daphne and laserdisc by the laserdisc player devices, gameandwatch and lcdgames by the handheld sources, any other (arcade, mame, consolearcade) for every machine. The published installer copy of the index leaves the sources out. Manifests: RetroDECK gains 1399 files, 378.2 MB, below roms/. Of the 219 sets named as read outside the BIOS folder, 58 reach 146 files (25.9 MB), 161 stay named, no command's machine reading them. 441 sets RetroDECK's list also declares at bios/ reach 1253 files (352.3 MB), 429 each in arcade and mame and 480 in consolearcade. No other platform changes.
