6.14 — Quality-of-life bundle — Idle Startup Steam update #177202

A round of polish from your forum feedback. Speedrun times now show seconds — your "fastest run" Hiscores read like 2m 14s instead of rounding to a whole minute, so steady improvements actually show up. The window remembers its size — reopen the game at whatever size you left it last time. Tidier save management — "Manage Saves" and "Delete Save" are now a single Manage Save File screen. Each copy (Steam Cloud / This Device) has its own delete button, so you can clear a specific copy without touching the one you're playing. Plus a fix so confirmation pop-ups always appear on top of the menu they came from. Thanks to Loop, Ducimus and LostEnigma_ for the suggestions!
