Three fixes for HTTP response correctness: 1. HEAD requests: Deno.serve already strips bodies from HEAD responses. The explicit \ ew Response(null, result)\ wrapper was unnecessary and could produce incorrect Content-Length headers (RFC 7231 §4.3.2). Remove the special case and let Deno handle it. 2. Malformed URI params: \decodeURI()\ throws a URIError on malformed percent-encoding (e.g. %GG), causing an uncaught 500 error instead of a proper 400. Wrap in try/catch and fall back to the raw value. 3. DiskBuildCache.readFile(): Replace the \�sync\ + lint-ignore pattern with an explicit \Promise.reject()\ to cleanly signal the intentional not-implemented status.

Malformed URI params: \decodeURI()\ throws a URIError on malformed percent-encoding (e.g. %GG), causing an uncaught 500 Internal Server Error. Wrap in try/catch and fall back to the raw value so the handler can respond appropriately.
DiskBuildCache.readFile(): Replace the \�sync\ + \deno-lint-ignore require-await\ pattern with an explicit \Promise.reject(), which is cleaner and signals the intentional not-implemented status without requiring a lint suppression.
