hdrprobe v0.3.0

New

• Mastering primaries mismatch verdict. When a Dolby Vision grade's own L9 mastering gamut disagrees with the mastering display the base layer signals (MDCV box or ST.2086 SEI), the DV Mastering line now carries an MDP mismatch badge, the classic signature of re-encode drift such as a BT.2020-claiming MDCV over a P3-D65 grade. The verdict fires only when both sides are recognized gamuts from real signaling; it is never guessed.
• L10-defined custom trim targets. The trim-target set now includes custom target displays defined by the title's global L10 metadata even when no sampled trim referenced them, folded into the L8 set. This most often surfaces the authored target list of Profile 20 titles.
• Reports stream as files finish. In multi-file runs each report prints the moment its file completes instead of waiting for the whole run. On interactive terminals a finished file's progress display is erased in place, so the screen accumulates clean reports with the live scan bar always at the bottom. Piped, quiet, and JSON output is byte-identical to before; only the timing changes.
• Dividers and counts in multi-file runs. Consecutive reports are separated by a divider, and each report header carries a [k/N] counter.
• Terminal-width layout. Long value lines now reflow at natural separators to fit the terminal, and section rules and the between-reports divider stretch to the full terminal width. Piped and redirected output keeps its historical fixed-width formatting byte-for-byte.
• Folder context-menu scan (Windows). The explorer integration adds a folder verb that scans a directory recursively, alongside the existing per-file verb. Re-install using --install-shell to pickup the new capability.

Schema

• 1.1 to 1.2 (additive). The JSON report adds dolby_vision.mastering_primaries_mismatch, and trim_targets now also includes target displays defined by the title's global L10 metadata, folded into the L8 set (a semantic broadening of levels: [8], no new field or value). Documented in docs/SCHEMA.md.
