A token cannot contain tokens: next to a token `a`, the tokens `a.b`
and `a.b.c` are now invalid with tokenscript, whatever the order of
their sets. As with StyleDictionary, their pills and the token form
show "Group name of a.b conflicts with a token of the same name in
another active set." and `{a.b}` is a missing reference.
The interpreter reports them as :processor/token-name-collision, which
the adapter maps to :error.token/name-collision. frontend/deps.edn
updates penpot/tokenscript-interpreter to v0.2.0, which adds the check.
Since v0.1.0 its errors carry codes and data only, which the adapter
already relies on.

Replace the @penpot/tokenscript npm package (the TypeScript
interpreter) with penpot/tokenscript-interpreter, a Clojure and
ClojureScript interpreter that now lives in its own repository and
compiles into the frontend build.
The frontend adapter (app.main.data.tokenscript) resolves tokens with
it behind the existing :tokenscript flag and maps its results to the
values and errors the workspace uses:
- Token values are validated by the interpreter's token types, passed
by their DTCG names: `1foo` is not a dimension, a number has no
unit, an opacity is between 0 and 1. Penpot only adds its own
limits (font weight names, text decoration keywords).
- Division by zero, incompatible units, unknown functions and
function arguments out of range get messages of their own, and
token pills show the message of their error.
- Font family names are quoted before resolving, as in the adapter
this replaces (#11750): `Red Hat` stays one name.
The token form's value input passed the token name to the tokenscript
resolver in place of the typed value, and no name at all for a new
token. It now resolves the typed value under the form's token name, as
the StyleDictionary path does.
StyleDictionary stays the default until the interpreter is stable.
frontend/deps.edn pins the interpreter by tag and commit, v0.1.0.
