Smooth Streaming manifests carry no range attributes, so every ISM video track was labelled SDR even when the stream is HDR10/HLG/DV, breaking range-based selection (-r HDR10 / -r DV) for ISM services. - ism_init: walk the full HEVC SPS (incl. scaling-list and st_ref_pic_set skippers) to read the VUI colour triple (colour_primaries, transfer_characteristics, matrix_coeffs); expose parse_codec_private_data_colour() keyed by FourCC. No unshackle imports added. - ism: new ISM.get_video_range() maps the CICP triple via Video.Range.from_cicp (PQ -> HDR10, HLG -> HLG, BT.709/absent -> SDR); DVHE/DVH1 FourCCs map straight to DV since DV bitstreams signal Unspecified (2,2,2) in the VUI. to_tracks() now sets range_ on every video track. Soft-fails to SDR on malformed data. - ism: accept RnetSession in download_track() so TLS-impersonated sessions pass the type check. - tests: real PQ/HLG/BT.709 (x265-minted) and Dolby Vision (live-manifest, DoViProfile=stn, out-of-order SPS,PPS,VPS NALs) CodecPrivateData samples; byte-level VUI assertions in test_ism_init and manifest->Range characterization in new test_ism_range.
