Adds PdfBuilder.linkRect() for /Subtype /Link annotations with a
/Dest pointing at another page's destination. TOC entries record a
target placeholder that the per-step loop fills in once it knows
which page the step landed on, so clicking a Contents line jumps the
reader straight to that step.
writeDescription/emitBlocks rendered each word as a separately positioned
Tj, advancing by our approximate average-glyph-width estimate — which is
much wider than real space/character widths, producing "This is bold"
style gaps. Render each line as one continuous text object instead
(PdfBuilder.textRun), so consecutive Tj operators advance using the
viewer's real font metrics.

PDF exports now preserve bold/italic/links/lists/blockquotes from the
description editor (via a new HTML block/run parser) instead of flattening
to plain text. Literal "[text](url)" links inserted by the editor's Link
button are converted to real <a> tags before rendering. Tabs and common
"smart typography" characters (smart quotes, dashes, ellipsis, bullet) are
mapped to their WinAnsiEncoding glyphs instead of rendering as "?".
