feat(cli): improve file discovery and completion

- Render remote files as an aligned table with JSON and TSV alternatives.
- Add Bash and Zsh completion for commands, options, paths, and remote files.
- Allow downloads by exact filename while rejecting ambiguous duplicate names.
- Cover table formatting, completion scripts, and selector resolution with tests.
