Sprite Forge v0.3.0

Added

• Lua-scripted custom formats: drop a .lua script into the scripts folder to add a new file format with its own categories, load dialog title, and read/write logic; no app rebuild required.
• Tools → Lua Scripts dialog with an enable/disable toggle, script browser, and syntax-highlighted Lua editor for live edits and reloads.
• Format scripts declare their own property schema (sections, fields, visibility, grids), so each format shows only the editor controls it actually supports.
• Slice/crop editor window with layers, marching-ants selection, transform mode, rectangular pixel select, proximity grid snap, and layer keyboard ops.
• New project dialog (File → New…) for creating empty .dat/.spr projects with version, transparency, extended, frame groups, and improved animations toggles.
• Right-click Import… on an item to replace it; when multiple objects are selected in the import dialog, the first replaces the clicked item and the rest are added as new.
• In-app confirm modal for replace flows.
• Auto-calculate exact size for items from their non-transparent pixel bounds.
• Expanded client version table to cover 7.10–12.86.
• Fallback to .otfi metadata + version 1099 when the DAT signature is unrecognized.

Fixed

• Sprite optimizer now applies the temp file atomically and refuses to overwrite the original with itself, eliminating a case where the SPR file could be deleted on compile.
• Light, Displacement, and Minimap fields no longer appear twice on wide property panels; the Visuals block and the body columns share a single breakpoint.

Performance

• Faster compiles on large projects: the DAT file is no longer rewritten when only sprites changed, and the backup copy runs in parallel with sprite-state capture instead of blocking the write.
