Remove temp cut buffer commands and cleanup related SourceView code

- Moved cut_to_temp_buffer and paste_temp_buffer commands to plugin
- Remove temp buffer state and timeout logic from SourceView
- Remove associated keybindings (Ctrl+K / Ctrl+U)
- Ignore "buffer" pseudo-path when filtering loaded files
- Ensure view receives focus after DnD file load
