fix(canvas/config): skip config.yaml fetch for external / hermes runtimes — eliminate 404 console noise

Browse Source 
Reported on production reno-stars 2026-05-05 (browser console):

  /workspaces/d76977b1-…/files/config.yaml:1
    Failed to load resource: the server responded with a status of 404

The workspace was an external-runtime mac-mini-style agent that
doesn't use the platform's config.yaml template — every Config tab
open issued a GET that 404d cleanly, and the existing catch block
fell into the runtime-manages-own-config branch + populated the
form from workspace metadata. Functionally correct, but the request
fired anyway, surfaced as a 404 in DevTools, and burned an RTT.

Fix: branch on RUNTIMES_WITH_OWN_CONFIG BEFORE the fetch — when the
workspace's runtime is one of those (external, hermes), skip the
GET, populate the form from workspace metadata directly, set
loading=false, return. Same code path as the existing 404-catch
fallback, just skipping the wasted request.

Behavior preserved for runtimes that DO use the template
(claude-code, etc.): unchanged GET → parse → setConfig flow.

Tests: 24/24 existing ConfigTab tests pass; no behavioral change for
the documented runtimes. tsc clean.
