Subject: [PATCH] fix(app): use precise hostname match instead of substring for
 opencode.ai

Replace String.includes() with a regex that only matches opencode.ai
and *.opencode.ai. The previous substring match caused false positives
on domains like opencode.aid.example.com, forcing the backend URL to
localhost:4096 instead of location.origin.

Fixes #39479
