Adds a Ships window that scans the stage containers, reconstructs each capital ship from its XBG7 part family (via sylpheed_formats::ship), and renders the whole assembled model in the 3D view on click. - iso_loader: ShipBrowser resource + ShipRow (id, faction, name, parts, stage, and linked Vessel stats: HP/size/turrets/bridges/shield gens), RequestShipCatalog + RequestShipRender events, ShipCatalogLoaded message. build_ship_catalog scans Stage_S01..S30, groups resources into ships, joins Vessel recipes by id, and sorts capital ships (Vessel-matched) first. handle_ship_render_request decodes only the ship's parts (models_named) and assembles them off-thread, reusing the existing XprPrepared → apply_prepared_xpr render + camera-focus path. - prepare_models gains an `assemble` mode (prepare_ship): parts share ONE recentre so each keeps its ship-local offset (bridge fore, engines aft) instead of the per-model recentre / thumbnail grid used for a stage browse. - ui: draw_ships_ui (own system, keeps draw_viewer_ui under the 16-param limit) — faction filter chips, name/id search, collapsible per-ship stat cards with an "Assemble & view in 3D" button; colour-coded by faction.
