Publish page dropdowns (namespace/visibility) failed to open on older Chromium because Vite 6 defaults build target to chrome87 and some bundled deps call runtime APIs absent in Chrome 83 (replaceAll, .at, hasOwn). Lower esbuild/vite target to chrome83, add browserslist, drop ??= in bootstrap, and inject runtime polyfills before main loads.

/**
|
|
* Polyfills for older browsers (e.g. Chromium 83 on Debian 10) that lack a few
|
|
* ES2021+ runtime methods used by bundled dependencies. esbuild only transpiles
|
|
* syntax, not runtime APIs, so we patch the prototypes here before any other
|
|
* module runs.
|
|
*
|
|
* TypeScript's lib target is ES2020, so the methods we patch are referenced via
|
|
* string keys / loose casts to avoid compile-time type errors.
