New `observe` option: resolve Solid's observe builds for production observability. `observe: true` adds the `observe` export condition to every environment — client and server, inlined and externalized (`resolve.externalConditions`), inlining the core runtime and its consumers for server builds the way the dev posture already does so one build is loaded end to end — and turns on the compiler's `componentNames` option, so component owner labels (`<Home>`) survive minification in diagnostics and attribution paths. `componentNames` is also enabled under the dev posture, where `lazy()` and HMR wrappers otherwise hide the tag name. Requires `@solidjs/compiler` / `@solidjs/babel-plugin` ≥ 2.0.0-rc.8 (the release that adds the option).

#### options.observe

- Type: Boolean
- Default: false

Resolve Solid's observe builds in production: the production-speed runtime that keeps the
diagnostics and attribution channels (`OBSERVE`) alive for observability tooling (error
monitoring, performance tracing). Adds the `observe` export condition to every environment
and turns on the compiler's `componentNames` option, so component owner labels (`<Home>`)
survive minification. Under `vite dev` the dev build still wins.
