Behaviour

• ⌘ Enter reveals the selected app, pane, or $PATH program in Finder (NSWorkspace.activateFileViewerSelecting).
• ⌥ Enter copies the item's path to the clipboard.
• ⌃ Enter opens a new instance of the app (OpenConfiguration.createsNewApplicationInstance). For $PATH programs it just runs them in the terminal again.
• Alternate actions only apply to a selected item. With no match, they do nothing (typed text is not run).
• Shift Enter still runs the typed text. Shift wins when it is combined with another modifier.
• Piped stdin (PipeListProvider) and any provider without alternate actions fall back to plain Enter through a default ListProvider.doAction(item:action:).

Implementation

• New src/ItemAction.swift: the ItemAction enum (mapping from modifiers), isSubmit (modified Returns reach the field editor as insertNewlineIgnoringFieldEditor: (⌥), insertLineBreak: (⌃), or noop: (⌘), and the Return keyCode check stops ⌃O from triggering it), and FileActions, whose workspace and pasteboard calls can be swapped out in tests.
• ListProvider gains doAction(item:action:) with a default implementation. AppListProvider, CommandListProvider (which now keeps each program's full path), and CompositeListProvider implement it.
• SearchViewController changes are limited to the Enter branch and an optional action parameter on submit.
• README Keys table updated.

Testing

• New ItemActionTests cover the modifier mapping, submit detection, the FileActions pasteboard, reveal, and new-instance actions, routing through the App and Composite providers, and the fallback for plain providers. There are also new tests in SearchViewControllerCommandTests and CommandListProviderTests.
• xcodebuild ... test: 227 tests, 0 failures.
• swiftlint --strict: 0 violations.
