available in the standard library since Go 1.21.

pbkdf2 is too expensive to run in init, so this change makes it load
lazily. I introduced a lazy package that I hope to use more in my
`GODEBUG=inittrace=1` adventure.
Benchmark results:
```
$ hyperfine "coder --help" "coder-new --help"
Benchmark 1: coder --help
Time (mean ± σ): 82.1 ms ± 3.8 ms [User: 93.3 ms, System: 30.4 ms]
Range (min … max): 72.2 ms … 90.7 ms 35 runs
Benchmark 2: coder-new --help
Time (mean ± σ): 52.0 ms ± 4.3 ms [User: 62.4 ms, System: 30.8 ms]
Range (min … max): 41.9 ms … 62.2 ms 52 runs
Summary
coder-new --help ran
1.58 ± 0.15 times faster than coder --help
```
1. Adds benchmarks comparing bcrypt and our pbkdf2 settings
1. Changes the pbkdf2 hash iterations back to 65k. 1024 is insecure
1. Gets rid of the short circuit when the user isn't found, preventing
timing attacks which can reveal which emails exist on a deployment

Customer feedback indicated projects was a confusing name.
After querying the team internally, it seemed unanimous
that it is indeed a confusing name.
Here's for a lil less confusion @ashmeer7 🥂
* chore: Fix golangci-lint configuration and patch errors
Due to misconfiguration of a linting rules directory, our linter has not been
working properly. This change fixes the configuration issue, and all remaining
linting errors.
* Fix race in peer logging
* Fix race and return
* Lock on bufferred amount low
* Fix mutex lock
* feat: Add authentication and personal user endpoint
This contribution adds a lot of scaffolding for the database fake
and testability of coderd.
A new endpoint "/user" is added to return the currently authenticated
user to the requester.
* Use TestMain to catch leak instead
* Add userpassword package
* Add WIP
* Add user auth
* Fix test
* Add comments
* Fix login response
* Fix order
* Fix generated code
* Update httpapi/httpapi.go
