perf(core): pack the named-color table

[pbroom]

Store the 141 distinct CSS Color 4 keywords as one alphabetical,
prefix-coded string (a digit for the letters shared with the previous
name, then the rest) plus one string of fixed-width rrggbb values,
decoded into a Map on first lookup. grey spellings still fold onto gray
and transparent is added separately.

parse + toHex + contrastRatio: 5336 B -> 5233 B gzip (-103 B)
everyday toolkit: 5380 B -> 5281 B gzip (-99 B)

Add a test that the packed table decodes to exactly the CSS Color 4
keyword list (checked against colorjs.io).

Part of the color-kit assessment stack (#204 → #227). Build, test, lint, typecheck, format, size and check:artifacts pass.

Confidence Score: 5/5

[Medium risk] Repacks the named color lookup table for bundle size.

The PR appears safe to merge; no actionable issues were found.

What we checked:

• Longer hex values still parse: parse passes the result to hexToRgb, which accepts both lengths. It also expands the unchanged 0000 value into transparent black.

Summary

Packs CSS named colors into prefix-coded names and fixed-width hex values. namedColorTable decodes them once, on first lookup.

• Keeps grey aliases and transparent.
• Adds full-table checks against colorjs.io, plus checks for invalid names.
• No actionable issues found. Tests were not run.
