refactor: rename verboseMode to compactMode for better UX clarity (#3075)

The "Compact Mode" label is more intuitive than "Verbose Mode" for users,
as it directly describes the default compact view experience. This change
inverts the boolean semantics (compactMode=false means show full output)
and exposes the setting in the /settings dialog (showInDialog: true).

- Rename ui.verboseMode → ui.compactMode with inverted default (false)
- Rename VerboseModeContext → CompactModeContext (file and exports)
- Rename TOGGLE_VERBOSE_MODE → TOGGLE_COMPACT_MODE in key bindings
- Update all consumer components with inverted logic
- Update i18n keys across 6 locales (verbose → compact)
- Update VS Code settings schema
- Add ui.compactMode documentation to settings.md
- Fix Ctrl+O description in keyboard-shortcuts.md
