The statusline uses a hardcoded 80% scaling factor for context usage,
but Claude Code's actual autocompact buffer is 16.5% (usable context is
83.5%). This inflates the displayed percentage and causes the context
monitor's WARNING/CRITICAL thresholds to fire prematurely.
Replace the 80% scaling with proper normalization against the 16.5%
autocompact buffer. Adjust color thresholds to intuitive levels
(50/65/80% of usable context).
Closes#769
