Refer to #12603 for part 1. We need to be careful when migrating to the new API, because the new API has slightly different semantics (PWD can contain symlinks). This PR handles the "obviously safe" part of the migrations. Namely, it handles two specific use cases: * Passing PWD into `canonicalize_with()` * Passing PWD into `EngineState::merge_env()` The first case is safe because symlinks are canonicalized away. The second case is safe because `EngineState::merge_env()` only uses PWD to call `std::env::set_current_dir()`, which shouldn't affact Nushell. The commit message contains detailed stats on the updated files. Because these migrations touch a lot of files, I want to keep these PRs small to avoid merge conflicts. |

Welcome to the standard library of `nushell`!
The standard library is a pure-nushell collection of custom commands which
provide interactive utilities and building blocks for users writing casual scripts or complex applications.
To see what's here:
> use std
> scope commands | select name usage | where name =~ "std "
#┬───────────name────────────┬──────────────────────usage──────────────────────
0│std assert │Universal assert command
1│std assert equal │Assert $left == $right
2│std assert error │Assert that executing the code generates an error
3│std assert greater │Assert $left > $right
4│std assert greater or equal│Assert $left >= $right
... ...

🧰 Using the standard library in the REPL or in scripts
All commands in the standard library must be "imported" into the running environment
(the interactive read-execute-print-loop (REPL) or a .nu script) using the
use command.
You can choose to import the whole module, but then must refer to individual commands with a std prefix, e.g:
use std
std log debug "Running now"
std assert (1 == 2)
Or you can enumerate the specific commands you want to import and invoke them without the std prefix.
use std ["log debug" assert]
log debug "Running again"
assert (2 == 1)
This is probably the form of import you'll want to add to your env.nu for interactive use.
