Incorrect context usage display in status bar #4743

What version of the VS Code extension are you using?

Version 0.5.17

Which IDE are you using?

Visual Studio Code – Insiders 1.105.0-insider

What platform is your computer?

Microsoft Windows NT 10.0.26120.0 x64

What steps can reproduce the bug?

Open a Codex chat/session (gpt-5-codex).
Paste a long prompt to increase context usage.
Check the status bar/tooltip that shows context counts and percent

What is the expected behavior?

Percentage should be within 0–100% and keep its decimal (e.g., 74.46%, 27.76%)

Numerator/denominator should be formatted consistently:

• either both scaled with k (e.g., 20.3k / 272k tokens)
• both raw with grouping (e.g., 20,293 / 272,000 tokens)

No mixing of thousands grouping with a k suffix

What do you see instead?

Status bar shows inflated percentages like 7461% and 2762% where the real values are ~74.46% and 27.76%
Numerator renders as 20,293k (reads as “20,293 thousands” ≈ 20.293M) though it means ~20.3k

Additional information

Observed progression (from a single session, same 272k limit):
12k / 272k tokens → 4%
24k / 272k tokens → 9%
209k / 272k tokens → 77%
251k / 272k tokens → 92%
320k / 272k tokens → 118% ← exceeds 100%
344k / 272k tokens → 127% ← exceeds 100%
