fix(tui): preserve renderer initialization errors

[Hona]

Summary

• preserve the original OpenTUI renderer initialization error instead of Effect.tryPromise's generic fallback
• cover native library loading failures with a lifecycle regression test

Related to #33903 and #32706.

Testing

• bun test test/app-lifecycle.test.tsx --timeout 30000
• bun typecheck (packages/tui)
• bunx prettier --check packages/tui/src/app.tsx packages/tui/test/app-lifecycle.test.tsx
• pre-push workspace typecheck (29 packages)

The full TUI suite passes 191 tests but retains one unrelated Windows path separator failure in test/runtime.test.tsx: expected ~/project, received ~\project.
