* chore: update deps, fix escape codes, expand tests, add README - Bump Go 1.18 → 1.26, simplecolorpalettes v0.9.5 → v0.9.7 - Fix swapped fg/bg ANSI escape code values in trueColorString - Expand test suite from 2 to 13 tests (determinism, positivity, color assignment, background contrast, stringer palette) - Add README with usage examples * feat: add OKLCH-aware palette generation Add GenerateOKLCHPalette() which creates n evenly-spaced colors in the OKLCH color space at a given lightness and chroma. This produces perceptually uniform palettes where all colors appear equally bright. Uses the new OKLCH support from simplecolorpalettes. Note: go.mod contains a replace directive for local development that must be removed before merge (after simplecolorpalettes is published). * build: update simplecolorpalettes to v0.9.8 (charmtone palette)
