Crate loran_render 

Loran renderer — Markdown body → terminal output.

v1 ships a single mode: ANSI-free plain text suitable for any POSIX terminal and for piping into grep / awk / cut / sed (PRD quality goal Q-03, NFR-050). TUI rendering with the Spacecraft Software palette is deferred to Phase 2 (Billet).

Output rules (Spec §10, kept minimal so the same renderer can drive both loran show and the rare cases where we render a tldr body):

• Headings become a blank line, the heading text in UPPER CASE (Standard “primary text” convention for non-coloured surfaces), another blank line.
• Paragraphs become a text line followed by a blank line.
• Lists are emitted with - bullets, with two spaces of indentation per nesting level. Numbered lists are still bullet- formatted; numerical ordering is not preserved in v1 because the Spacecraft Software catalog content does not rely on it.
• Code blocks indent every contained line by four spaces. Fence info-strings are dropped.
• Inline code becomes `text`.
• Links become text (url) — visible URLs for terminal users who cannot click.
• Raw HTML is passed through verbatim.
