refactor(bridge): update listFiles to listDirectory tool

Rename `vscode_list_files` to `vscode_list_directory` to accurately
describe its functionality. Introduced a legacy case to maintain
backward compatibility with older tool calls. Updated UI strings,
icons, and execution handlers to support the new tool name and its
parameters.
