📜 Description

Adds a new test file PropagationTargetsUtilsTest.kt with 14 focused unit tests for PropagationTargetsUtils, which previously had zero test coverage.

Tests cover:

• Empty origins list → returns false
• Substring matching (origin found within URL)
• Regex matching (valid regex origin matched against URL)
• Invalid regex gracefully falling back to substring check
• Multiple origins (first-match-wins behavior)
• Exact full-URL match
• Partial matches (URL prefix, path segment)
• URI overload delegation to the String-based method
• Negative cases for each of the above

💡 Motivation and Context

PropagationTargetsUtils controls whether Sentry trace headers are attached to outgoing HTTP requests — a critical piece of distributed tracing. Despite this, the class had no dedicated unit tests. This PR closes that gap with a small, low-risk, test-only change.

💚 How did you test it?

./gradlew :sentry:test --tests "*PropagationTargetsUtilsTest*"
# All 14 tests PASSED

./gradlew :sentry:spotlessApply
# Formatting clean, no changes needed

Reviewer checklist

• Verify the regex-path tests (lines 28–36) genuinely exercise the url.matches(origin) branch rather than the url.contains(origin) branch (they do — the regex literal is not a substring of the test URL).
• Confirm no important edge cases are missing (e.g., origins with special characters, very long URLs).

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Other sentry/util classes with zero test coverage that could benefit from the same treatment:

• SampleRateUtils (partially covered), ClassLoaderUtils, ErrorUtils, ScopesUtil, UUIDStringUtils
