fix(desktop): ignore log links in output cards (#714)

Output target detection should not promote URLs or markdown links embedded in fenced log/code blocks into assistant output cards. Keep explicit localhost and file references outside code blocks routable.

Tested: cd desktop && bun run test -- src/lib/assistantOutputTargets.test.ts src/components/chat/AssistantMessage.linkrouting.test.tsx
Tested: cd desktop && bun run lint
