[BUG] statusLine command receives "high" instead of "xhigh" for effort level

What's Wrong?

When effort is configured to xhigh, the JSON passed to a statusLine command reports "level": "high" in the .effort.level field instead of "xhigh". This makes it impossible for a status line script to distinguish between high and xhigh effort.

What Should Happen?

Expected: .effort.level = "xhigh"
Actual: .effort.level = "high"

Error Messages/Logs

Steps to Reproduce

1. Set effort to xhigh (/effort xhigh)
2. Configure a statusLine command that reads .effort.level from the piped JSON
3. Observe the value is "high", not "xhigh"
