- Use a basic heuristic to auto enable `--dev-client` when
`expo-dev-client` is in the project `package.json`. Users can swap to
Expo Go with `s` or pass `--go` to ensure Expo Go is the default target.

# Test Plan

- Added basic option tests.
- Updated the docs.

[cli][packages] unify the default dev server port to 8081 (#22880)

# Why

for historical reasons, when running `npx expo start` the dev-server listens to port 19000, and running `npx expo start --dev-client` it listens to port 8081. since we are now on our effort to deprecate `--dev-client` option, it is better to unify the listening port.
close ENG-8936

# How

- update packages/**/*.ts for port 19000 -> 8081
- search more occurrences for 19000 to 8081

# Test Plan

- ci passed
- bare-expo
- unversioned expo go + ncl

feat(cli): add --go option to expo start (#22925)

# Why

We're going to be adding a system to change the default launch mode
based on if dev client is installed. This will enable users to force the
default behavior in case the default algorithm isn't what they want.
Also adds `-d` alias for dev client, and stops marking `--dev-client` as
experimental.
