[codex] Add file tree context actions

[BunsDev]

Summary

• add workspace file tree context menus for files, directories, and search results
• add native shell RPCs to open directories and reveal files in Finder or the platform file manager
• cover the new shell routes and file-manager launch behavior with server tests

Why

The file tree had no right-click actions, so common desktop workflows like opening a directory in Finder or revealing a file externally were missing. This change fills that API gap instead of handling it as a web-only workaround.

Impact

Users can now right-click file tree entries to open files, open in the preferred editor, reveal files in Finder, open directories in the system file manager, and copy absolute paths.
