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.
