79744afd41Two packaging bugs: 1. The './schema.json' export pointed to dist/src/generated/schema.json but nothing copied it there (tsc is emitDeclarationOnly, Bun.build doesn't emit JSON). Consumers got ERR_MODULE_NOT_FOUND. Fix: cpSync after tsc runs. 2. zod is a peerDependency but was bundled into every entry point (~270KB each). This causes dual-instance bugs where consumer-side 'instanceof ZodError' and schema.extend() break across boundaries. Fix: add zod to external list for all non-with-deps entries. Bundle size impact: app.js 293952 -> 24561 (-91.6%) app-bridge.js 299517 -> 30112 (-89.9%) react/index.js 295558 -> 26153 (-91.2%) server/index.js 291500 -> 22135 (-92.4%) app-with-deps 321814 -> 321814 (unchanged, intentional)
