feat: show REPO and PLAYLIST columns by default in list --all-repos

[proboscis]

Summary

• Show REPO column by default when using runbox list --all-repos (previously required --verbose)
• Add PLAYLIST column showing the playlist display name for playlist items
• Include playlist_name in JSON output when --all-repos is used

Changes Made

crates/runbox-cli/src/main.rs

• Added playlist_name: Option<String> field to RunnableInfo struct
• Changed condition from if verbose to if show_repo (where show_repo = all_repos || verbose)
• Added PLAYLIST column to table output header and rows
• Populated playlist_name from storage when show_repo is true

crates/runbox-core/src/storage.rs

• Added get_runnable_playlist_name() method to retrieve playlist display name for runnable items

crates/runbox-cli/tests/list.rs

• Added test_list_all_repos_shows_repo_and_playlist_columns test
• Added test_list_all_repos_json_includes_playlist_name test

Example Output

Before:

SHORT      TYPE       SOURCE           NAME                     TAGS
────────────────────────────────────────────────────────────────────────
abc12345   playlist   game_run[0]      tpl_game_cli             -
def67890   template   -                tpl_echo                 -

After (with --all-repos):

SHORT      TYPE       SOURCE           NAME                     TAGS   REPO                     PLAYLIST
──────────────────────────────────────────────────────────────────────────────────────────────────────────
abc12345   playlist   game_run[0]      tpl_game_cli             -      /path/to/game-repo       Card Game 2026
def67890   template   -                tpl_echo                 -      /path/to/runbox          -
