upgrade: script-loader package upgrade for Solid 2.0

[davedbase]

Imports isServer, assign, ComponentProps, and JSX from @solidjs/web (previously solid-js/web / solid-js)

• Replaced the removed splitProps with plain JS iteration to extract src, event handlers, and static attributes
• Static props now applied via assign(script, staticProps, true) synchronously — this is actually an improvement over the original setTimeout(() => spread(...)) because attributes like type and async are now set before the script is appended, which is the correct browser behavior
• Event listener registration moved outside the reactive effect (handlers are static, no need to re-register reactively)
• createRenderEffect converted to the split compute/apply form: `createRenderEffect(() => srcValue, src => { ... })
