refactor(Mountain): Decompose Utilities module into explicit submodules

Split the monolithic Utilities.rs into 7 domain-specific modules under WindServiceHandlers/Utilities/: ApplicationRoot, ChannelPriority, JsonValueHelpers, MetadataEncoding, PathExtraction, RecentlyOpened, and UserdataDir. Update all call sites in FileSystem/Native handlers, Scheme.rs, WindowBuild.rs, and AppLifecycle.rs to use explicit module paths (e.g., `Utilities::PathExtraction::extract_path_from_arg`) instead of flat imports.

This continues the module decomposition pattern from recent commits, replacing the catch-all Utilities module with granular domain-specific handlers. The explicit reverse-hierarchical paths make dependency relationships clear at every call site, consistent with CLAUDE.md requirements.

Also reverts binary/lib names in Cargo.toml and tauri.conf.json to the verbose development profile format, matching the pre-simplification state.
