Add tab completion for commands and file paths
Implement tab completion in interactive mode using rustyline:
- Command completion: /<TAB> shows all commands, /com<TAB> -> /compact
- File path completion: /run <TAB> completes file/directory paths
- Supports tilde expansion for home directory
Architecture is extensible for future semantic completions:
- /resume <TAB> -> session IDs (Phase 2)
- /rehydrate <TAB> -> fragment IDs (Phase 2)
New module: completion.rs with G3Helper struct implementing
rustyline's Completer trait.
