VS Code extension: inline usage indicator shows stale percentage vs Account & Usage panel (93% vs 100% for same 5hr session limit)

Bug description

In the VS Code extension, the inline usage warning above the input box and the Account & Usage panel report different values for the SAME metric (5-hour session limit) at the same moment:

• Inline warning above input box: "You've used 93% of ..."
• Account & Usage panel (and /usage): Session (5hr) = 100%

The inline indicator appears to be a stale/cached value that only updates after a request completes, while the panel fetches current data. This is confusing because the user believes they still have headroom when the limit is actually already exhausted.

Environment

• Claude Code version: 2.1.204
• Platform: Windows 10 Education 10.0.19045
• Interface: VS Code extension
• Plan: Claude Pro

Steps to reproduce

1. Work until close to the 5-hour session limit
2. Compare the inline usage warning above the input box with the Account & Usage panel / /usage output
3. The panel consistently shows a higher (more current) percentage than the inline indicator

Expected

Both surfaces should show the same, current percentage, or the inline indicator should refresh when displayed.

(Screenshot attached showing 93% inline vs 100% in the panel.)
