Inlines bodies of reco_get_home, reco_get_home_ml, and reco_get_home_resolved
from reco_store/commands.rs directly into the v2 wrappers in
commands_v2/library.rs. Promotes their shared helpers
(get_home_seeds_internal, resolve_tracks, resolve_artists,
album_to_card_meta) from private to pub(crate) so the v2 wrappers can
call them without crossing back into a legacy command module.
Deletes the corresponding legacy #[tauri::command] definitions and
prunes now-unused imports from reco_store/commands.rs.
Step 8 of legacy cleanup, group G.
