fix: remove PREPARING/ANALYZING intermediate badge deploys

Root cause: Cloudflare Pages serves stale deployments when multiple
deploys race to the same branch. The ANALYZING placeholder deployed
seconds before the final report would sometimes 'win' the race.

Fix: Only deploy once — the final report with the real badge. No more
intermediate PREPARING or ANALYZING placeholders.
