…HTTP Router resolvePrefixedPath now strips trailing slashes off the prefix before joining, preventing double slashes when prefix already ends with `/`. Router.resolve normalizes incoming request paths the same way (preserving `/` itself) so a route registered with path `/` under prefix `/api` matches both `/api` and `/api/`. Closes #5252
Replace `replace(/\/+$/, '')` with a small `stripTrailingSlashes` helper that walks the string from the end, keeping path normalization linear in input length.

Summary
Routerregistered route ids did not handle trailing slashes consistently: a root route under a prefix (e.g.app.get('/', …)withprefix: '/api') was unreachable from/api/, and a prefix that accidentally ended with/produced double slashes in the route id (e.g.'/api//users'), breaking matches.Changes
resolvePrefixedPathnow strips trailing slashes from the prefix before joining, so'/api'and'/api/'produce the same result and no//appears in the route id.Router.resolvenormalizes incoming request paths the same way (preserving/itself), so a route registered as/under prefix/apimatches both/apiand/api/.resolvePrefixedPathcovering prefix-with-trailing-slash inputs, and integration tests inbasic-routing.test.tsfor both bug scenarios from the issue.resolvePrefixedPathJSDoc to document the normalization preconditions.Issue number: closes #5252
