Extends the platform to handle 7 new image format families alongside the existing AVIF support gap-fill. Uses the established HEIC decoder pattern (CLI decode → PNG → Sharp) for formats Sharp can't handle natively: Camera RAW via dcraw_emu/LibRaw, PSD/TGA/EXR/HDR via ImageMagick. JXL and ICO are Sharp-native. Adds server-side preview for non-browser-displayable formats and JXL as a new convert output target. All 27 validateImageBuffer callers updated with filename for extension-based format detection.
