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.

Problem: Premiere reads Radiance HDR (.hdr) pictures; FilmCraft listed
the extension nowhere and could not open them.
Fix: clean-room RGBE decoder in filmcraft-media from the public format
description: header with FORMAT, all eight axis orders, flat, old
run-length and new per-channel run-length scan lines. Frames are linear
float (Rec.709), like EXR. Allocations are bounded by the data present;
hostile headers and truncated data return errors. "hdr" joins the
importable still extensions; stills and image sequences share the decoder.
Output equals ffmpeg's decode exactly for flat and RLE files; EXPOSURE and
PRIMARIES lines are ignored and XYZE is refused.

A tiny header naming ~1000 channels on a 64M-pixel line sized each chunk
buffer at hundreds of GB and Vec::with_capacity aborted the process.
Chunks over 256 MB are refused, and the RLE / zlib buffers reserve with
try_reserve_exact. Regression test: huge_scan_lines_are_refused_before_allocating.

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.

Problem: FilmCraft exports OpenEXR sequences (#806) but could not open
.exr files at all, so EXR plates and renders from other apps could not
be imported (docs/gaps.md G10).
Fix: a clean-room OpenEXR reader in filmcraft-media (still/exr.rs) for
single-part scan-line files with no, RLE, ZIPS or ZIP compression and
half / float / uint channels, with our own zlib/DEFLATE decoder (no new
dependency). R, G, B, A (or luminance Y) become premultiplied linear
RGBA float frames, the compositor's working format, so values above 1.0
survive; the data window is placed in the display window. Stills open
through open_bytes, sequences through ImageSequenceSource; tiled, deep,
multi-part, subsampled and PIZ / PXR24 / B44 / DWA files are refused
with a clear error.

Problem: Premiere imports Targa and DPX as stills and numbered sequences.
FilmCraft exports both (#779) but could not read either: the extensions
were not importable and the image crate has no DPX reader, so even our
own Targa / DPX renders could not come back in.
Fix: clean-room decoders in filmcraft-media. Targa from the TGA 2.0 spec:
image types 1/2/3 and RLE 9/10/11, colour maps, 15/16/24/32-bit, 8/16-bit
grayscale, any origin. DPX from SMPTE ST 268: first element, luma / RGB /
RGBA / ABGR, 8/16-bit, filled 10/12-bit (methods A and B), either byte
order, padded lines, orientations 0-3. Both bound allocations by the
data present and reject hostile headers with errors. Stills and image
sequences share one decode_raster entry point; "tga" and "dpx" join the
importable still extensions.

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.
- Update MediaInfo to store all discovered audio streams in audio_streams
- Retain independent stream metadata and decoder state for MP4/MOV and Matroska/WebM
- Update audio_placement_specs to allocate successive tracks via ensure_audio_tracks
- Isolate clip rendering to read assigned audio stream rather than replaying stream 0
- Bump project schema to v13 with backwards compatibility for legacy v12 projects
Resolves#312Fixes#200Fixes#315
- Lumetri grades PQ / HLG working spaces in their own signal normalised to
HDR White (Basic Correction) / HDR Range (Curves) in cd/m²
(filmcraft_color::GradeSpace): exposure in stops of light, highlights above
HDR White kept, HDR Specular scales them; Rec. 709 unchanged.
- HDR static metadata (mdcv/clli, Matroska MasteringMetadata/MaxCLL/MaxFALL)
on VideoStreamInfo::hdr; PQ media use MaxCLL / mastering peak as the
BT.2390 source peak; media.colorInfo reports it.
- HSL Secondary Refine: Denoise (median of the key) and Blur (Gaussian).
- Lumetri Presets (18 original looks in 4 folders) with thumbnails rendered by
our Lumetri on a procedural preview picture; Effects panel rows and a
thumbnail grid when wide; lumetri.presets / applyPreset / presetThumbnails.
- Color Match: Comparison View toggle; Apply Match uses its reference frame.
- Goldens lumetri_hdr_pq and lumetri_presets_grid; D-Log M stays unsupported
(no published formula).
