fix[sdk][studio]: ENG-13439 boolean targeting in Builder Studio

[floating-dynamo]

Description

• This fixes boolean targeting rules that failed because Studio sent string values instead of booleans.
• Convert Studio user attribute values "true" and "false" back to booleans before sending the Content API request.

Note

Low Risk
Small, Studio-preview-only change to query parsing with a focused unit test; no auth or persistence impact.

Overview
Fixes boolean targeting in Builder Studio preview by normalizing user-attribute query values before they are sent to the Content API.

When preview=BUILDER_STUDIO, builder.userAttributes.* URL params are parsed via parseStudioUserAttribute, which turns string "true" / "false" into real booleans (other values stay unchanged). A test covers mixed boolean and string attributes plus the existing urlPath / host injection.

Patch bumps all framework SDK packages via changeset.

Review Details

Code Review Summary

PR #4830 fixes Builder Studio preview targeting by normalizing the URL-derived builder.userAttributes.* values "true" and "false" into JSON booleans before the Content API URL is generated. The implementation is narrowly scoped to the existing BUILDER_STUDIO path, preserves other attribute values, and continues to add the current pathname and host. The regression test covers both boolean values, a regular string attribute, and the generated context attributes. The changeset includes the affected SDK packages.

Risk assessment: Low. This is a focused SDK preview-parsing change with no authentication, persistence, mutation, or API-contract changes.

No confirmed bugs were found by either parallel code-review agent. The test suite was not executed because the workspace dependency setup failed while building isolated-vm; this is an environment limitation rather than a finding in the patch.

🧪 Browser testing: Skipped — dev server unavailable on HEAD due to failed workspace setup (isolated-vm build failure and no dev command configured). Will retry on the next incremental review.
