Trevor BrownandClaude Sonnet 5.5 35d46208cf M4: Shared open loops all close through their segment; one index per rounding pass (#1951) ...

Two regions over one open chain both got the closing segment when rounded, but reopen_loops gave it to the first loop only, so after an unrelated deletion the second region's curved closing segment dropped out of its fill. The pass now takes the segment for every loop that walks the same chain (same segment set); a different chain still can't share it.

closing_segment no longer scans every segment and every loop per call: rounded_smoothed and reopen_loops build one LoopIndex (endpoint pair to segments, and which segments are in a loop) per pass and pass it in.
