Bust Cargo cache to force Rust widget rebuild

[rileyseaburg]

Summary

• Bump Cargo cache version from v2 to v3 to force full Rust rebuild
• Bump widget_renderer version to 0.1.3

Problem

The previous deployment did not include the modal button fix because CircleCI was using a cached version of the Rust library. The cache key was based only on Cargo.lock, not the Rust source code (template_renderer.rs), so source code changes didn't trigger rebuilds.

Solution

Bump the cache version to invalidate the old cache and force a fresh build of the Rust widget renderer with the modal button fix.

Pull request overview

This PR busts the CircleCI Cargo cache to force a complete rebuild of the Rust widget renderer library. The previous deployment failed to include a modal button fix because CircleCI cached the compiled Rust library based only on Cargo.lock, not the Rust source code changes.

Key changes:

• Bumped Cargo cache version from v2 to v3 to invalidate existing cache
• Bumped widget_renderer version from 0.1.1 to 0.1.3

The version is being bumped from 0.1.1 to 0.1.3, skipping 0.1.2. While this doesn't break functionality, it's unconventional and could cause confusion about what happened to version 0.1.2. If 0.1.2 was deployed but didn't include the modal button fix due to the cache issue, consider whether the version should follow sequential numbering for better version tracking. If there's a specific reason for skipping 0.1.2 (e.g., it was already tagged but not deployed correctly), this is acceptable but should be documented.

Suggested change

	version = "0.1.3"
	version = "0.1.2"
