[BUG] Usage limit does not reset to 0 after 5-hour/weekly reset — shows already-consumed usage with no activity

What's Wrong?

Description
After the 5-hour usage limit resets, the counter does not start at 0. Instead it immediately
shows a significant chunk already consumed (roughly 80k-100k tokens, or ~57-59% of the weekly
limit in one observed case) before any new request has been made in the fresh session.

This is not a one-off — it happens consistently on every reset I've observed.

Steps to reproduce

1. Use Claude Code until the 5-hour usage limit is reached / blocked.
2. Wait for the limit to reset (shown in the UI countdown, e.g. "Resets Thu, Aug 13, 3:00 PM").
3. Open Claude Code again, before sending any new message.
4. Check the usage indicator (context window / plan usage limits panel).

Expected behavior
Usage counter should start at 0 (or close to 0) immediately after reset, since no requests
have been made in the new window yet.

Actual behavior
Usage counter shows a substantial amount already consumed (e.g. 80k-100k tokens / ~57-59%
of weekly budget) despite zero activity since the reset.

What Should Happen?

Usage counter should start at 0 (or close to 0) immediately after the reset, since no requests have been made in the new window yet. Instead, it shows a significant chunk already consumed (e.g. 80k-100k tokens, or ~57-59% of the weekly limit) right after reset, with zero activity in between.

Error Messages/Logs

No console error or crash — this is a display/accounting discrepancy in the usage limit UI panel, not a runtime error. See attached screenshots for the exact numbers shown before and after reset.

Steps to Reproduce

1. Use Claude Code until the 5-hour usage limit is reached / blocked.
2. Wait for the limit to reset (shown in the UI countdown, e.g. "Resets Thu, Aug 13, 3:00 PM").
3. Open Claude Code again, before sending any new message.
4. Check the usage indicator (context window / plan usage limits panel).
