- drop unused widgets (AnimatedStateSwitcher, GridSkeleton,
adjacentHorizontalPageRoute, buildRemovalAnimation, SwingIcon,
BottomSheetOptionTile) and empty _buildInfoCard placeholders
- drop test-only Go wrapper methods (GetDownloadURL, MatchTrack,
CheckAvailability 7-arg, CustomSearchForItemID) and their parsers
- drop unused httputil getters/validators and hand-rolled base64
decoder in favor of encoding/base64
- remove unused riverpod_generator dev dependency
gofmt -r rewrite of all 506 interface{} occurrences to the any alias
(identical semantics), drop unused spec constants into comments, rename
unused parameters to _, convert three if-else chains to tagged
switches, and use slices.ContainsFunc for the private-IP check. No
behavior change; the whole package is now gofmt-clean.
Pure mechanical move within package gobackend — no signature or behavior
change. extension_providers.go (3,798 lines) now holds only the
extensionManager provider-listing/orchestration methods; DTOs, goja value
conversion, the provider wrapper methods, download fallback, and priority
state moved to extension_{provider_types,goja_convert,provider_wrapper,
fallback,priority}.go.
