Conrad Ludgate 72832b3214 chore: fix clippy lints from nightly-2025-03-16 (#11273)
I like to run nightly clippy every so often to make our future rust
upgrades easier. Some notable changes:

* Prefer `next_back()` over `last()`. Generic iterators will implement
`last()` to run forward through the iterator until the end.

* Prefer `io::Error::other()`.

* Use implicit returns

One case where I haven't dealt with the issues is the now
[more-sensitive "large enum variant"
lint](https://github.com/rust-lang/rust-clippy/pull/13833). I chose not
to take any decisions around it here, and simply marked them as allow
for now.

Local Development Control Plane (neon_local)

This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command. This is a convenience to invoke the neon_local binary.

Note: this is a dev/test tool -- a minimal control plane suitable for testing code changes locally, but not suitable for running production systems.

Example: Start with Postgres 16

To create and start a local development environment with Postgres 16, you will need to provide --pg-version flag to 3 of the start-up commands.

cargo neon init --pg-version 16
cargo neon start
cargo neon tenant create --set-default --pg-version 16
cargo neon endpoint create main --pg-version 16
cargo neon endpoint start main

Example: Create Test User and Database

By default, cargo neon starts an endpoint with cloud_admin and postgres database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.

cargo neon endpoint create main --pg-version 16 --update-catalog true
cargo neon endpoint start main --create-test-user true

The first command creates neon_superuser and necessary roles. The second command creates test user and neondb database. You will see a connection string that connects you to the test user after running the second command.
