Thank you for improving Nushell. Please, check our [contributing

-->
Currently `parse` acts like a `.filter` over an iterator, except that it
emits `None` for elements that can't be parsed. This causes consumers of
the adapted iterator to stop iterating too early. The correct behaviour
is to keep pulling the inner iterator until either the end of it is
reached or an element can be parsed.

- this PR should close #9906

Enable macOS foreground process handling (#9909)
# Description
Currently, foreground process management is disabled for macOS, since
the original code had issues (see #7068).
This PR re-enables process management on macOS in combination with the
changes from #9693.

# User-Facing Changes
Fixes hang on exit for nested nushells on macOS (issue #9859). Nushell
should now manage processes in the same way on macOS and other unix
systems.

Add an option to set header on border (style) (#9920)
fix #9796

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.

Fix default prompt indicators (#9914)
related to
- https://github.com/nushell/nushell/pull/9907

# Description
https://github.com/nushell/nushell/pull/9907 removed the front space
from all `PROMPT_INDICATOR`s but this is not what the default behaviour
of Nushell is, i.e. in `nu --no-config-file`.

this PR
- removes the space that is prepended by Nushell before the prompt
indicator to match the `default_env.nu`
- swaps INSERT and NORMAL in the Rust code to match the `:` and `>`
respectively in `default_env.nu`

## 🔍 try the changes
> **Warning**
> i had to comment out in my config all the `$env.PROMPT_INDICATOR... =
...` to avoid these variables to propagate to `cargo run -- -n`

in either `cargo run -- -n` or `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu`,
- see `/path/to/nushell>` as the prompt with the default `emacs` edit
mode
- run `$env.config.edit_mode = vi`
- see `/path/to/nushell:` as the INSERT prompt in Vi mode
- press Escape to go into NORMAL mode
- see `/path/to/nushell>` as the NORMAL prompt in Vi mode
- press I to go back into INSERT mode
- see `/path/to/nushell:` as the INSERT prompt in Vi mode

# User-Facing Changes
the prompts in `nu --no-config-file` and `nu --config default_config.nu
--env-config default_env.nu` should be the same 😌

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

Revert "Add an option to move header on borders" (#9908)
Reverts nushell/nushell#9796

This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).

Add an option to move header on borders (#9796)
A patch to play with.
Need to make a few tests after all.

The question is what shall be done with `table.mode = none`, as it has
no borders.

```nu
$env.config.table.move_header = true
```

rename from date format to format date (#9902)
# Description
Closes: #9891
I also think it's good to keep command name consistency.

And moving `date format` to deprecated.

Running `date format` will lead to deprecate message:

Simplify default style and match Rust code to config (#9900)
# Description

This PR aligns the default config in the Rust code to the default config
in the nushell file.

To do so, it removes closures from the default file, opting instead to
pick a simple style as default. This allows easier maintenance of both
Rust and Nushell code without removing the ability to use closures for
styling in your configuration.

The default theme is now "dark mode" in both the Rust and nushell config
code.

Obligatory screenshot:

Relative: #8248 

After this pr, user can define const variable inside a module.

![image](https://github.com/nushell/nushell/assets/22256154/e3e03e56-c4b5-4144-a944-d1b20bec1cbd)

And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):

![image](https://github.com/nushell/nushell/assets/22256154/b2c14760-3f27-41cc-af77-af70a4367f2a)

## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`

## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.

It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.

What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.

## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

Replace &Span with Span since Span is Copy (#9770)
# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.

# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.

Accept records for http subcommand headers (-H) (#9771)
# Description

See also: #9743 
Before: 
`http <subcommand> -H` took a list in the form:

```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```

Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
    Cookie:  "acc=barfoo",
    User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```

is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```

# User-Facing Changes

Add format duration to replace into duration --convert (#9788)
# Description
Add `format duration` cmd to choose output unit.

This takes the previous `into duration --convert ...` behavior which
returned a string into its own `format duration` command.
This was suprising and not fitting with the general type signature for
the `into ...` commands.

This command for now lives in the `nu-cmd-extra` nursery.

# User-Facing Changes
## Breaking change
Removes formatting behavior from `into duration`
Now use `format duration` instead of `into duration --convert`
## Usage:
```
1sec | format duration us # Output data in microseconds
"2ms" | into duration | format duration sec # go from string to string
```

allow print to take data as input again (#9823)

# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of 
```nushell
print "foo"
```

this PR enables the `any -> nothing` input / output type to allow this
again.

i've double checked and `print` is essentially the following snippet
```rust
        if !args.is_empty() {
            for arg in args {
                arg.into_pipeline_data()
                    .print(engine_state, stack, no_newline, to_stderr)?;
            }
        } else if !input.is_nothing() {
            input.print(engine_state, stack, no_newline, to_stderr)?;
        }
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`

# User-Facing Changes
```nushell
"foo" | print
```
works again

Fix the implied collect type to 'any' (#9827)

Previously, we had a bug slip in about implied collection caused by
`$in`, that this output type would be of type `string`.

The type system fixes in 0.83 now make this more visible and cause

At some point in the future, we may want to carry the type through where
we can, but `any` should unblock using `$in`.

Remove Signature.vectorizes_over_list entirely (#9777)
# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.

Simplifies the example testing a bit.

# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

Fix signatures for cellpath access of records (#9793)
# Description
The same procedure as for #9778 repeated for records.

# User-Facing Changes
Commands that directly supported applying their work directly to record
fields via cell paths, that worked before #9680 will now work again

# Tests + Formatting
Tried to limit the need to add new `.allow_variants_without_examples()`
by adjusting or adding tests to also use some records with access.

# Description

This fixes the type of `$rest` to be a `List<...>` so that it properly
is checked in function bodies.
