Instant preset switch, silent lock, fractional zoom 

- Preset combobox now loads preset instantly on selection (no OK needed)
- Lock file silently prevents duplicate instances (no alert popup)
- Zoom supports fractional levels (0.125x, 0.25x, 0.5x) for large tilesets
- All zoom handlers use zoomStep() with predefined level table
