I work in PST -- I am not going to bed [Driving Me Crazy]

### Describe the bug

I work in the PST time zone, and Co-pilot CLI thinks I am working in UTC -- no matter how many times I tell it I am working in PST. I wouldn't really care, but it keep telling me it has been a long day, are you ready to stop for today?It is after midnight, should we stop. Which is driving me nuts.

### Affected version

GitHub Copilot CLI 1.0.12-1

### Steps to reproduce the behavior

Want me to have CBG update the NPC plan with all 13 fixes now? Or should we call it a night and queue this for tomorrow? - this is at 8:24 in the morning.

### Expected behavior

_No response_

### Additional context

_No response_

Start by reproducing the time-related prompts in GitHub Copilot CLI 1.0.12-1 while working in the PST time zone, then trace where the CLI determines the current time and timezone. Done means the CLI respects the user's local timezone and no longer reports that the day has ended at the wrong local time.
