Claude Code enforces an 80% context window limit as a safety mechanism.
The statusline was showing the raw percentage, which meant the bar never
reached 100% before Claude ran out of context.
This change scales the percentage so that:
- 0% real usage = 0% displayed
- 80% real usage (the actual limit) = 100% displayed
Color thresholds are adjusted accordingly to maintain the same visual
progression (green -> yellow -> orange -> red with skull).
