Explore alternatives to JSON.parse

[WULCAN]

Description

Store#loadFromDisk uses JSON.parse to reload unpublished translations from disk after restart. JSON.parse is a blocking API so this might block the main thread for a long time.

Explore if we can replace this blocking API.

Estimated size (S, M, L)

I think this issue is Small because only the research is in scope. We will spawn a new issue for any implementation.

Open questions

This could potentially never get prioritized, as it only affects one request after restart.

To avoid blocking the main thread with JSON.parse, we can use a streaming JSON parser like stream-json.
This allows us to process the JSON data in chunks, which can help prevent blocking the main thread.
