fix: correct core extras placement for retrodeck and romm packs

Browse Source 
RetroDECK: core extras with subdirectory paths (e.g. vice/C64/,
fbneo/, dc/) were placed outside bios/ because the prefix was only
inferred for bare filenames. Add _detect_extras_prefix() to infer
the dominant BIOS prefix from YAML destinations.

RomM: core extras landed flat at bios/{file} instead of the required
bios/{platform_slug}/{file}. Add _detect_slug_structure() to detect
per-system slug layouts and _map_emulator_to_slug() to route each
extra to the correct slug subfolder.

Also skip manifest writes when only the generated timestamp changed,
preventing unnecessary diffs in install/*.json.
