node:http: missing argument/header/URL validation (assert.throws → Missing expected exception) #4907

Summary

Node:http performs argument/header/URL validation that throws on bad input. Under Perry these validations are absent, so the test's assert.throws(...) fails with Missing expected exception (Perry accepts the bad input silently).

Validations missing

• Header name/value: validateHeaderName / validateHeaderValue — invalid header field chars must throw ERR_INVALID_HTTP_TOKEN / ERR_INVALID_CHAR (test-http-invalidheaderfield.js, test-http-response-add-header-after-sent.js, test-http-response-remove-header-after-sent.js)
• Request path/method: invalid path chars (test-http-invalid-path-chars.js), unescaped path (test-http-client-unescaped-path.js), invalid method (test-http-request-invalid-method-error.js)
• Host header as array must throw (test-http-client-headers-host-array.js)
• URLs: invalid URLs / non-http(s) protocol must throw (test-http-invalid-urls.js, test-http-url.parse-only-support-http-https-protocol.js)
• insecureHTTPParser option validation (test-http-client-insecure-http-parser-error.js, test-http-insecure-parser-per-stream.js, test-https-insecure-parse-per-stream.js)
• Content-Length mismatch detection (test-http-content-length-mismatch.js)
• early hints invalid argument (test-http-early-hints-invalid-argument.js)

Acceptance

Bad header names/values, paths, methods, host-array, non-http protocols, and invalid options throw the matching ERR_* so the tests' assert.throws passes.
