`npubs` commands fail with cryptic "Only POST is supported." when no auth proxy is configured

[bilthon]

Description

On a plain local install (no daemonUrl and no authUrl configured), running any npubs command crashes with an unhandled error that has nothing to do with what the user typed.

Steps to reproduce

routstrd onboard      # standard local setup, no remote/auth proxy
routstrd npubs list

Output:

76 |     body: bodyString,
77 |   });
78 | 
79 |   if (!response.ok) {
80 |     const errorData = (await response.json()) as { error?: string };
81 |     throw new Error(errorData.error || `HTTP ${response.status}`);
               ^
error: Only POST is supported.

Bun v1.1.42 (macOS arm64)

Expected result

A clear message explaining that npubs requires a routstrd-auth server, e.g.

Environment

• routstrd dev build (local bun link)
• Bun v1.1.42, macOS arm64
