chore: remove unused tslib dependency

[JuroUhlar]

tslib was a runtime dependency but the built output (dist/fingerprint-vue.js / .mjs) contains zero references to it — the es2020 target emits no TS helpers, and Vite would inline any that were needed. Removes unnecessary weight from consumers' node_modules.

Verified: pnpm build clean, grep tslib dist/* returns 0, 27/27 tests pass.
