Compute the final ASCII frame-number boundary without slicing inside a UTF-8 character. Preserve Unicode prefixes and add parser and public image-sequence import regressions, including missing frames and timeline placement.
Fixes#1565

Problem: .dng files were not importable, and a DNG (a TIFF) would have
gone to the TIFF decoder, which reads at best the embedded preview. A
CinemaDNG shot (a folder of numbered DNG frames) could not be edited.
Fix: "dng" joins the importable still extensions. filmcraft-media
develops DNGs with filmcraft-dng into scene-linear Rec. 709 float
frames (transfer Linear, like OpenEXR), so highlights above 1.0 reach
the compositor. A single DNG is a still; a numbered folder imports
through the existing image-sequence path as one clip, whose frame rate
and start time code come from the first frame's CinemaDNG FrameRate and
TimeCodes tags (else Settings > Media > Indeterminate Media Timebase).
Lossy and JPEG XL DNGs are refused as unsupported by name.

Camera files such as CLIP.MOV were hidden or skipped on Linux because sibling matching and tests assumed lowercase suffixes. Import, the media browser, and image-sequence numbering now accept mixed-case extensions.
Headless import merged into the current project, so a demo or leftover timeline mixed into export. replace:true starts from file.newProject with the same name, then imports, which is the documented empty-project-start workflow.
