fix: treat protocol-less host:port URLs as valid in isURL

[codefix-patchflow]

What failed

URL returns false for urls like some-hostname:9000 after 13.15.20 version bump, 13.15.15 works as expected returning true Examples validator.isURL("my-3272-service:9000", { require_tld: false, require_valid_protocol: false }); // returns false in 13.15.20 Additional context Validator.js version: 13.15.20 Node.js version: 22.14.0 OS platform: linux

What changed

Patchflow applied a minimal source change for the reported failure.

• src/lib/isURL.js around line 115 (modified, +32/-25)
• test/validators.test.js around line 499 (modified, +1/-0)

Why this works

The parser distinguishes a numeric host:port suffix from a protocol delimiter, so protocol-less service hostnames continue through normal host and port validation while require_protocol still rejects URLs without an explicit protocol.
