Route paths now only match at proper segment boundaries. Previously /travel-plan incorrectly matched /travel-plans. Changes: - Updated path matching logic to check for exact match or trailing slash - Added unit tests for path matching edge cases

Problem
The Router's CloudFront function uses simple
startsWith()matching for paths, causing incorrect route matching when paths share a common prefix.For example:
/travel-planincorrectly matches/travel-plans/apiincorrectly matches/api-docsSolution
Updated the path matching logic to check for proper path segment boundaries. A path now only matches if:
/, OR/Changes
CF_ROUTER_INJECTIONinplatform/src/components/aws/router.ts(line ~1541)platform/test/components/router-path-matching.test.tsTesting
The test file duplicates the path matching logic rather than importing it because the actual implementation lives inside a CloudFront function string literal. This allows testing the logic in isolation without complex string parsing.
Verified with live CloudFront deployment:
/travel-planscorrectly does NOT match route/travel-plan/travel-plan/abccorrectly matches route/travel-planBreaking Changes
None. This is a bug fix that corrects unexpected behavior.
