ToJs

Typeclass for values that can be safely interpolated into JavaScript via js"...".

This is a '''templating''' typeclass, not a code generator. It converts Scala values into JavaScript '''expressions''' (value literals). Every JavaScript expression is also a valid statement, so ToJs output works in all template contexts: inline event handlers, script content, and variable assignments. For JavaScript control flow (if/for/while), use Js("...") directly.

Instance behavior:

• String is quoted with " and JS-escaped (including `` protection)
• Numeric types render as unquoted literals
• Boolean renders as true/false
• Option renders as the value or null
• List/Map render as JSON arrays/objects
• Types with a zio.blocks.schema.Schema auto-derive via JSON serialization
