fix(builder): use terser minification to preserve wagmi TLA initialization (#320)

esbuild's minification reorders statements in a way that breaks Top-Level
Await (TLA) initialization in wagmi connectors, causing runtime errors like
"Cannot set properties of undefined (setting 'type')" in production builds.

Changes:
- Remove wagmi from manualChunks (code splitting exacerbates TLA issues)
- Set build target to esnext to preserve native TLA syntax
- Switch from esbuild to terser for minification (preserves TLA order)
- Configure terser to not mangle top-level names

This fixes EVM and Polkadot adapters failing to load networks in Docker/
production builds while working correctly in development mode.
