Mitchell Hashimoto 63e75e86c2 lib-vt: many more color utility APIs (#13206) ...

Embedders that render theme editors, palette pickers, or custom settings
UI need to use the same color semantics as Ghostty.

This moves the shared parsing paths into terminal/color and exposes them
through libghostty-vt. Config color and palette parsing now delegate to
the same helpers, so CLI/config behavior and the C ABI stay in lockstep.

From C:

    GhosttyColorRgb rgb;
    ghostty_color_parse("ForestGreen", 11, &rgb);

    uint8_t index;
    ghostty_color_parse_palette_entry(
        "0x10=#282c34", 12, &index, &rgb);

    const GhosttyColorX11Entry* names =
        ghostty_color_x11_names();

The exported color API is:

    ghostty_color_parse
    ghostty_color_parse_x11
    ghostty_color_parse_palette_entry
    ghostty_color_palette_default
    ghostty_color_palette_generate
    ghostty_color_luminance
    ghostty_color_perceived_luminance
    ghostty_color_contrast
    ghostty_color_x11_names
    ghostty_color_x11_name_count

The X11 name table is parsed once at comptime into null-terminated
entries in rgb.txt order. The existing case-insensitive map keeps the
same behavior for RGB.parse and +list-colors, while bindings can walk a
static table without allocations.

This doesn't add any more binary size since all of this was already used
by terminal internals.
