Subject: [PATCH 1/2] fix(star-tracker): de-inflate chart-view counts +
 per-repo breakdown

The chart preview rendered two <img> tags (light + dark) with CSS
toggling visibility, so every page load fetched both variants and
doubled the logged chart-view count. Switch to one <img> swapped by
JS, and switch the landing-page auto-preview to <picture> so only
the matching theme actually fetches.

Also add a "Views by destination" breakdown in the Audience panel,
grouping by (repo, kind) so the owner can see which org/repo pages
and embedded charts are getting traffic.

Subject: [PATCH 2/2] feat(star-tracker): per-repo Audience panel on repo page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Owner viewing /:slug/:repo now sees an Audience panel scoped to just
that repo's chart and page views. Uses the same viewsSummary helper
with an optional repo filter. The "Views by destination" sub-section
is suppressed when scoped (only one destination — the repo itself).
