fix(cli): free resvg-wasm objects to avoid GC-finalizer crashes

rasterizeViaResvgWasm created Resvg / RenderedImage wasm-bindgen objects
and left them to the GC FinalizationRegistry to free. That finalizer
runs at non-deterministic GC time and can fire while the shared wasm
instance is mid-render, throwing "recursive use of an object detected
which would lead to unsafe aliasing in rust" as an unhandled error that
intermittently fails the test run.

Capture both objects and free() them in a finally block so cleanup is
deterministic and no finalizer is left to race. Added a test asserting
both free() calls happen.
