Bump Hellion Chat manifest version to 0.1.0

Reset the version line out of the inherited Chat 2 1.35.x range
into a Hellion-specific track that starts at 0.1.0 to make the
bootstrap status visible to anyone reading the Dalamud plugin
list. The yaml changelog now lays out the full feature set added
on top of Chat 2 (privacy filter, retention, cleanup, export,
wizard, theme, localization) and explicitly calls out the upstream
1.35.3 base under EUPL-1.2.
