Fix eve/react client bundle in Next

[ijjk]

Summary

• route the client agent-info schema through Eve's vendored compiled Zod entry instead of bare zod
• add a neutral client vendored bundle grouping and move Zod packages into it so eve/react does not share Node-oriented workflow chunks
• leave Node vendored bundles on Rolldown's normal CJS interop so workflow/eval runtime chunks still work in Node
• add a framework-next build scenario regression test for the eve/react client bundle

Tests

• pnpm --filter eve typecheck
• pnpm --filter eve exec oxfmt --check src/client/agent-info-schema.ts scripts/vendor-compiled/_shared.mjs scripts/vendor-compiled/zod.mjs scripts/vendor-compiled/zod-validation-error.mjs test/scenarios/framework-next-build.scenario.test.ts
• pnpm --filter eve exec vitest run --config vitest.unit.config.ts src/client/client.test.ts
• pnpm --filter eve exec vitest run --config vitest.scenario.config.ts test/scenarios/framework-next-build.scenario.test.ts
• pnpm exec eve eval --help (from e2e/fixtures/agent-basic-runtime)

Note: local pnpm --filter eve test:tui reached the credential-dependent test path and was stopped after confirming the previous startup/runtime import crash was gone. GitHub CI test:tui is passing on the latest run.
