Delete `Collection+Only.swift`, `Duration+Seconds.swift`, `FileManagerExtensions.swift`, `PipeAsStringHandler.swift`, and `URLExtensions.swift` from `Sources/SwiftExtensions/`. The same APIs now live in swift-tools-protocols as `@_spi(SourceKitLSP) public` declarations. Update each call site to add `@_spi(SourceKitLSP) import ToolsProtocolsSwiftExtensions` next to the existing `import SwiftExtensions`. Add the `_ToolsProtocolsSwiftExtensionsForPlugin` dependency and the `ToolsProtocolsSwiftExtensions=_ToolsProtocolsSwiftExtensionsForPlugin` module alias to the `SwiftSourceKitClientPlugin` target in both `Package.swift` and the corresponding `CMakeLists.txt`.
