mopac-pdf v0: markdown to beautiful PDFs via digest-pinned typst

Go CLI that turns the markdown currency of this stack (Redmine notes, Discourse posts, briefing output) into typeset PDFs: two embedded typst templates (report with title page/TOC/headers, dense brief), front-matter (title/subtitle/author/date/classification/template), GFM tables, and bar charts rendered in pure Go (go-chart) from fenced chart data blocks. Engine is a prebuilt typst 0.15.1 container pinned by digest and run --network none; PDF bytes to stdout or -o. Exit codes 0/1/2. All dev in docker (dev.sh/Makefile); unit tests + golden typst fixtures plus a host-side smoke against the real engine container. Generated with Crush Assisted-by: Crush:glm-5.2
