MARK-005 MED: quote-marker continuation lines break wrapped inline spans in blockquotes

StrictMark allows a blockquote continuation to carry the quotation marker (StrictMark :104), but mark_enter_quote (MARK.c:540) renders quote lines PER-LINE with no soft-wrap join — unlike paragraphs (and unlike list entries after MARK-001). A reflink wrapped across quote lines (> see [two / > words][1]) renders raw [two\nwords] plus a stray wrong link; quote text also skips the budget check paragraphs get. From the 2026-07-07 mark/ diagnostic review, orchestrator-verified by probe (<blockquote>\nsee [two\nwords]<a href="x.html">1</a> x\n</blockquote>). Method Issues.

Input

Context

Probe (2026-07-07): the wrapped-reflink snippet renders broken brackets + a mislabeled anchor on the fresh build.
The paragraph buffer already solves this (soft-wrap join at flush, then inline pass) — quotes bypass it.

Goals

Quote continuation lines join like paragraph lines (marker shed, single-space join), THEN the inline pass runs — wrapped links/emphasis resolve; the joined quote passes the same budget check as a summary.

Constraints

Repro-first; reuse the existing para buffer path (MARK-001's para_li precedent), no new accumulator.

Design decisions

TODOs

Repro: wrapped reflink across quote-marker lines resolves.
Route quote text through the para buffer; budget the join; suite green.

Blockers and bummers

Touches the same flush path as the uncommitted MARK-001 fix — land that first.
