Closes: #7853
I found that I want this feature too...
So I take over it, sorry for that @VincenzoCarlino

Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:

you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.
I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...
now that @rgwood has landed benches I want
to start experimenting with benchmarks related
to the parser.
For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...
Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...
Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...
It will also enable other crates going forward to
use BufferedReader. Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".
# Description
Fixes: #7216
Adds `interact-once` switch which numbers out the number of files to
delete and asks the user for confirmation.

* Remove unnecessary `#[allow]` annots
Reduce the number of lint exceptions that are not necessary with the
current state of the code (or more recent toolchain)
* Remove dead code from `FileStructure` in nu-command
* Replace `allow(unused)` with relevant feature switch
* Deal with `needless_collect` with annotations
* Change hack for needless_collect in `from json`
This change obviates the need for `allow(needless_collect)`
Removes a pessimistic allocation for empty strings, but increases
allocation size to `Value`
Probably not really worth it.
* Revert "Deal with `needless_collect` with annotations"
This reverts commit 05aca984456438dc05b1fe89221c4305cb5d6472.
The previous state seems to better from a performance perspective as a
`Vec<String>` is lighter weight than `Vec<Value>`
* Use only $nu.env.PWD for getting current directory
Because setting and reading to/from std::env changes the global state
shich is problematic if we call `cd` from multiple threads (e.g., in a
`par-each` block).
With this change, when engine-q starts, it will either inherit existing
PWD env var, or create a new one from `std::env::current_dir()`.
Otherwise, everything that needs the current directory will get it from
`$nu.env.PWD`. Each spawned external command will get its current
directory per-process which should be thread-safe.
One thing left to do is to patch nu-path for this as well since it uses
`std::env::current_dir()` in its expansions.
* Rename nu-path functions
*_with is not *_relative which should be more descriptive and frees
"with" for use in a followup commit.
* Clone stack every each iter; Fix some commands
Cloning the stack each iteration of `each` makes sure we're not reusing
PWD between iterations.
Some fixes in commands to make them use the new PWD.
* Post-rebase cleanup, fmt, clippy
* Change back _relative to _with in nu-path funcs
Didn't use the idea I had for the new "_with".
* Remove leftover current_dir from rebase
* Add cwd sync at merge_delta()
This makes sure the parser and completer always have up-to-date cwd.
* Always pass absolute path to glob in ls
* Do not allow PWD a relative path; Allow recovery
Makes it possible to recover PWD by proceeding with the REPL cycle.
* Clone stack in each also for byte/string stream
* (WIP) Start moving env variables to engine state
* (WIP) Move env vars to engine state (ugly)
Quick and dirty code.
* (WIP) Remove unused mut and args; Fmt
* (WIP) Fix dataframe tests
* (WIP) Fix missing args after rebase
* (WIP) Clone only env vars, not the whole stack
* (WIP) Add env var clone to `for` loop as well
* Minor edits
* Refactor merge_delta() to include stack merging.
Less error-prone than doing it manually.
* Clone env for each `update` command iteration
* Mark env var hidden only when found in eng. state
* Fix clippt warnings
* Add TODO about env var reading
* Do not clone empty environment in loops
* Remove extra cwd collection
* Split current_dir() into str and path; Fix autocd
* Make completions respect PWD env var
