GraphCompose v1.6.0 — "expressive" is out

After a focused v1.6 cycle, v1.6.0 is live on JitPack — the "expressive" release.

Three feature pillars and an architecture pass:

• Templates v2 — 14 CV and 14 paired cover-letter presets, theme-driven via BusinessTheme, with one-liner create(theme) factories. Inline markdown, active hyperlinks, slot-based multi-column layouts. Pixel-diff visual parity gate against the v1 reference renders.
• Composed primitives — ListBuilder.addItem(label, Consumer) for nested lists, DocumentTableCell.node(...) for any composable node inside a cell (paragraphs, lists, sub-tables), and CanvasLayerNode for pixel-precise free-canvas placement with clip-policy and atomic pagination.
• Architecture hardening — @Internal API stability marker on document.layout.*, public PdfFragmentRenderHandler SPI as the registration path for custom render handlers, DocumentRenderingException wrapping the convenience render path so buildPdf / writePdf / toPdfBytes no longer declare throws Exception, documented thread-safety contract.

Verify gate: 819 / 0 / 0 / 0. 26 runnable examples regenerate cleanly. Source-compatible with v1.5 on the engine surface; the Templates v1 → v2 carve-out is migration-noted with a full before/after table.
