feat(providers): add trae/windsurf/zed/workbuddy/codebuddy-intl + icons

- New providers: trae, windsurf, zed, workbuddy, codebuddy-intl (registry + executor, wired into executors/index.js + registry/index.js) - zed: port hosted cloud proxy from OmniRoute — RSA access-token → short-lived LLM token exchange (shared/zedAuth.js) + NDJSON {event}/{status}/[DONE] stream translated back to OpenAI via Claude/Gemini/OpenAI-Responses translators - Provider icons (128x128 png) for the 5 new providers - qoder + tokenRefresh provider tweaks Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

+// Zed hosted LLM aggregator — auth + model-catalog helpers.
+// Ported from OmniRoute open-sse/shared/zedAuth.ts (plain JS, no TS types).
+//
+// Zed's cloud (cloud.zed.dev) authenticates native apps with a self-generated RSA
+// keypair instead of a registered OAuth client_id/secret:
+//   1. Client generates an ephemeral RSA keypair.
+//   2. Sends the public key to zed.dev/native_app_signin.
+//   3. User signs in via browser; Zed redirects to a local callback with the
+//      access token RSA-encrypted against the public key.
+//   4. Client decrypts locally with the private key that never left the host.
+// No embedded client_id/secret — the credential is a per-login keypair.
