[EmDash] A Vitest Regression Guard for publicHoistPattern and ssr.optimizeDeps.include on Cloudflare Workers

A Vitest test that verifies every package in ssr.optimizeDeps.include is both hoisted to node_modules/ and resolvable — so a missing publicHoistPattern entry surfaces as a named, actionable test failure instead of exports is not defined deep inside a workerd stack trace.

[EmDash] Why @atproto/api Caused exports is not defined in workerd and How pnpm Hoisting + ssr.optimizeDeps.include Fixes It

@atproto/api is CJS and lives only in pnpm's content-addressable store, so Vite's SSR optimizer can't find or convert it — meaning raw CJS reaches Cloudflare workerd, which has no exports global, and crashes. The fix requires both hoisting the package via publicHoistPattern and listing it in ssr.optimizeDeps.include.
