`number` and `constant` tokens use `$gold`, but per the Rosé Pine palette spec they should be `$rose`

In src/template.json (source for all three Zed theme variants), the syntax mapping uses the wrong palette role for numeric and constant literals:

"constant": { "color": "$gold" }
"number": { "color": "$gold" }

According to the Rosé Pine palette spec, rose is the role for booleans/constants, while gold is reserved for string literals. number/constant are currently mapped to gold, which is incorrect according to the spec. This also diverges from other official ports (Sublime Text and VSCode map constant.numeric/constant.language to rose).

Proposed change in src/template.json:

"constant": { "color": "$rose" },
"number": { "color": "$rose" }

Side note: operator is currently $subtle — consider $pine (or maybe $iris) to make it more distinguishable from normal punctuation, but that's just a suggestion. (VS Code renders operators in pine, for reference)

Start with src/template.json, the source for all three Zed theme variants, and compare its constant and number mappings with the Rosé Pine palette spec. Change those mappings to the specified palette role, leaving the optional operator suggestion out of scope. Done means the template reflects the spec for both token types across generated variants.
