Subject: [PATCH 1/2] fix(plausible): honor scriptInput.src in bundle.resolve
 for self-hosted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The build-time bundle transformer calls `bundle.resolve()` with the merged
registry config to determine which URL to download. For Plausible, the
resolver only inspected `scriptId`/`extension` and always returned
`plausible.io`, so self-hosted users hit fetch failures (e.g.
`https://plausible.io/js/pa-<id>.js` → 404) at build time and runtime
overrides were never reached.

Honor `options.scriptInput?.src` first so self-hosted Plausible bundles
from the user-configured origin.

Fixes #768
