Cosmetic-only player setting (default 1.0, range 0.0-2.0, step 0.1)
that scales the time-bonus row shown in the win-summary modal's
score breakdown. Achievement thresholds, lifetime score totals, and
leaderboard submissions still use the raw values produced by
`solitaire_core::scoring`, so the multiplier never affects what gets
recorded — just what the player sees on the win screen.
- New `Settings::time_bonus_multiplier` field with `#[serde(default)]`
+ `sanitized()` clamp so older settings.json files load cleanly.
- New constants `TIME_BONUS_MULTIPLIER_{MIN,MAX,STEP}` re-exported
through `solitaire_data::lib`.
- `settings_plugin` adds a slider row under the Gameplay header
matching the existing tooltip-delay control.
- `win_summary_plugin` applies the multiplier when rendering the
time-bonus row of the score breakdown; "Off" label when 0.0.
