fix: remove typescript from dependencies

[benmccann]

typescript should be in devDependencies. the package distributes .mjs/.cjs files so doesn't require typescript in any way. typescript weighs over 20mb: https://pkg-size.dev/typescript

Bug Report

Name	Severity	Example test case	Description
Missing transitive dependency	Medium	Install the library as a dependency in a new TypeScript project and try to build it.	Moving typescript from dependencies to devDependencies prevents it from being installed as a transitive dependency, potentially causing type checking issues in consuming projects.
