No it won't. SQLite is a poor choice at handling this, period. With all those hacks it still doesn't make any sense over something like PostgresSQL which is designed for that use case.
Yet another reason why I dismiss this nonsense of vibe coding.
A single vps like 1-2 GB ram and 2 CPU can suffice 100s of your projects
SQLite can handle 100s of users easyily
And 99% of vibe coded projects won't grow further than 100s of concurrent users
