Compact inline icon links and quiet-page spacing

[0thernet]

What changed

• Add an IconLink inline presentation for icon-only destinations beside typographic content.
• Keep the inline link accessible and interactive without persistent button chrome.
• Reduce the quiet-site page's viewport-relative top spacing while preserving a roomier bottom margin.
• Prepare @hraness/ui 0.4.2 and update the generated bundle and portfolio inventory.

Why

The control-style IconLink is correct in toolbars, but its bordered square disrupts writing-list typography when used as a source link. Quiet-site pages also reserve too much space above the first heading on phone viewports.

Impact

Existing IconLink consumers retain their control presentation. Consumers opt into presentation="inline"; inline mode excludes action sizes and variants at the type level.
