[BUG] Statusline shows 0% context usage after exit/re-enter, contradicts `/context` command

What's Wrong?

The statusline context usage indicator displays 0% after exiting and re-entering Claude, but the /context command shows the
actual usage (e.g., 42%). This creates confusion about true context consumption.

What Should Happen?

Statusline should accurately reflect context usage percentage matching /context command output.

Actual behavior:

• Run /context → shows 83.4k/200k tokens (42%)
• Statusline shows 0%
