This covers both the cli-repl and browser-runtime-core packages, and includes work to verify that startup performance remains stable (or mitigations if not, e.g. by lazily loading the autocompleter package and its dependencies if mongosh is running in interactive mode).

Reminder:

Provide the user with the ability to opt-out of new, additional data collection, such as schema sampling. We will still detect database and collection names of the current database unconditionally.
