🤖 fix: improve coder runtime info

[ethanndickson]

Summary

• surface Coder CLI list parsing failures in the runtime UI and Storybook
• show logged-in Coder username + deployment URL in the runtime header

Background
Coder CLI parsing failures were showing up as empty lists, and the runtime header only displayed the username without the deployment context. We need clearer error visibility and login context in the Coder runtime UX.

Implementation

• return discriminated {ok,error} results for Coder list endpoints and render their errors
• plumb whoami data so the UI can show "Logged in as on "
• extend Storybook mocks and add parse-error stories for templates, presets, and workspaces

Validation

• make static-check
• bun test src/node/services/coderService.test.ts src/node/runtime/CoderSSHRuntime.test.ts

Risks
Low; changes are scoped to Coder runtime plumbing, UI messaging, and Storybook mocks.

Thanks for the note. We’re going to leave whoami revalidation as-is for now; if the user changes Coder deployments they can restart the app to refresh cached whoami data.

Responding to both items:

• P2 Badge Revalidate whoami before using deployment URL: We’re going to leave whoami revalidation as-is for now. If a user changes Coder deployments, they can restart the app to refresh cached whoami data.
• P2 Badge Refresh deployment URL after login changes: Same rationale — we’re not addressing cache invalidation in this change set. Restarting the app refreshes whoami and deployment URL.
