Make the Claude Code statusline follow the terminal palette

Browse source 
The nine colours were hardcoded One Dark RGB via 38;2;R;G;B, so they did not
follow the light/dark switch. Measured against the tangere backgrounds they are
fine on dark (4.25-10.80:1) but collapse on light: orange 1.78, amber 1.70,
yellow 1.63, and 'white' — used for the token total — at 1.35:1, effectively
invisible.

Switched to palette indices, which resolve through the terminal's own palette and
so follow the ghostty tangere-light/tangere-dark swap with no detection and no
cost per render. 'white' becomes 39, default foreground, since it means primary
text. All seven colours actually used get distinct indices; blue and yellow are
unreferenced but converted too, so no RGB is left behind.

Contrast now clears WCAG AA in both modes: 5.77-14.26:1 on dark, 6.32-20.61:1 on
light.

Trade-off: tangere has no orange and its palette 2 is teal rather than green, so
'green' reads teal and the warm colours sit closer together than the One Dark
originals did.
