return `{}` on json parse error

Description

opencode/packages/core/src/models-dev.ts

Line 192 in ca354f8

return JSON.parse(text) as Record<string, Provider>

The access to models.dev was blocked by my network environment and returned HTML, causing opencode to fail to start.
Suggestions:

If JSON parsing fails here, the accessed link or file should be explicitly printed in the logs
When JSON parsing fails, return {} instead of failing to start

This issue might be a duplicate of existing issues. Please check:

• opencode ERROR service=models.dev error=unknown certificate verification error Failed to fetch models.dev #12408: models.dev fetch fails due to network/certificate error causing opencode to fail to start — same root cause (inaccessible models.dev breaks startup)
• Black screen on startup when configured proxy is unavailable during bootstrap #23107: models.dev timeout during bootstrap causes black screen on startup — same scenario of network-blocked models.dev fetch leading to startup failure

If your issue is distinct (e.g., specifically about the JSON parse error path when HTML is returned rather than a timeout/cert error), please clarify how it differs from the above.

My issue was caused by firewall restrictions — a connection that should have returned JSON returned HTML instead, causing opencode to fail to start, and the error log was unclear and unhelpful.
