Overview

Emits PDF Link annotations for IDML hyperlinks. After a spread renders, walk each visible text frame, look up its story's hyperlink sources, resolve each to a URL via HyperlinkResolver, and emit /Subtype /Link annotations.

When a PositionTracker is supplied (render path), link rects are computed from the tracker's recorded line positions — giving per-source rect precision instead of frame-level. Without a tracker, links fall back to the frame's bounding box (the original TODO 78 behavior).
