Feat/zod v4

[coji]

This pull request primarily updates the project to use zod version 4, along with related dependency and schema changes. It also includes minor configuration updates and cleanup of unused dependencies in the pnpm-lock.yaml file.

Dependency Updates:

• Updated zod to version 4 in package.json and adjusted its references in pnpm-lock.yaml. This includes updating the @conform-to/zod dependency to be compatible with zod@4.0.14. [1] [2] [3] [4]

Schema Adjustments for zod v4:

• Updated zod schema definitions in app/routes/$handle+/posts.$id.edit/route.tsx and app/routes/welcome+/create_account/route.tsx to replace required_error with error, aligning with zod v4 syntax. [1] [2]

Codebase Cleanup:

• Removed unused dependencies and packages from pnpm-lock.yaml, such as zodix, @remix-run/server-runtime, and others. This reduces bloat and ensures compatibility with the updated zod version. [1] [2] [3] [4]

Configuration Updates:

• Enabled unstable_optimizeDeps in react-router.config.ts to improve dependency optimization.

Minor Changes:

• Removed trailing whitespace in biome.json.

Poem

A rabbit hopped through code today,
Swapped imports, nudged some errors away.
JSON neat, packages set anew,
A tiny flag to tune the queue.
Hooray — the build hops light and true! 🐇✨

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md.
