chore(release): prepare 0.8.6

Bumps all 47 packages, the root manifest and the VS Code extension to 0.8.6,
and rebuilds the editor compiler, language server and extension bundles that
embed the version.

The release carries the output delivery fix: camelCase outputs now reach
parent bindings, and 18 components emit through output.* instead of
hand-built CustomEvents. See the 0.8.6 migration entry for what changes for
consumers.

+// Scrollspy -- a table of contents that follows the reader.
+//
+//   <Scrollspy items='[{"label":"Overview","href":"#overview"}]' />
+//
+// Each href points at an element on the page. The runtime observes those
+// elements and moves aria-current to the link for whichever one is in view.
+//
+// The runtime writes the marker straight onto the links rather than into
+// component state. An IntersectionObserver callback fires long after the
+// client function that registered it has returned, and a state write made
+// there is dropped -- so the DOM is the only place the answer can live.
+//
+// NOTE: the style block uses /* */ comments only -- // is not a CSS comment
+// and silently swallows the rule that follows it.
