This will only ever run the closure one time, when needed, then cache the values, so long operations are only ever run once, or not at all if not necessary.
Another change is allowing multiple column names, and erroring when the user gives a column name, whereas previously the command would always return the pipeline input.
Also changed is the function signature, since `default` never supported ByteStream input, and this doesn't add it either. This change and the added error can be reverted if desired.

# Description
Move clear jobs to _after_ traversing them, in order to kill them.
# User-Facing Changes
None
# Tests + Formatting
It looks like it's only used once, in crates/nu-engine/src/exit.rs
Value is now always evaluated once if a closure, so there's no need for either `--no-eval` or `--eval-once`. The closure is also always run without any input.
Because of that, the column code can be deduplicated again, and the default value can be calculated once at the start of the function, so cells won't store `Value::Error` values anymore.
Fixes#15675
I've added relevant test cases to ensure coverage of the identified bug.
The issue originated from my crate and pertains to the bracoxide
dependency—a bug I’ve internally referred to as IgnorantNumbers. I’ve
submitted a fix and updated the bracoxide dependency accordingly.

Adds a new table mode called `single`, it looks like the `heavy` mode,
but the key difference is that it uses thinner lines. I decided on the
name `single` because it's one of the border styles Neovim uses, and
they look practically the same.

I was interested in how nu-shell handles glibc, especially older
versions of it. I figured out from the docs that ubuntu 20.04 is
utilized. However, in reality, github has deprecated ubuntu 20.04, and
the code for ci.yaml in github workflow clearly states that it is 22.04.
This is just a minor doc update to clarify forgotten information

This PR seeks to port over the `*_horizontal` commands in polars
rust/python (e.g.,
https://docs.pola.rs/api/python/stable/reference/expressions/api/polars.sum_horizontal.html),
which aggregate across multiple columns (as opposed to rows). See below
for several examples.
```nushell
# Horizontal sum across two columns (ignore nulls by default)

# Description
While working on something else, I noticed that
`Value::follow_cell_path` receives `self`.
While it would be ideal for the signature to be `(&'a self, cell_path)
-> &'a Value`, that's not possible because:
1. Selecting a row from a list and field from a record can be done with
a reference but selecting a column from a table requires creating a new
list.
2. `Value::Custom` returns new `Value`s when indexed.
So the signature becomes `(&'a self, cell_path) -> Cow<'a, Value>`.
Another complication that arises is, once a new `Value` is created, and
it is further indexed, the `current` variable
1. can't be `&'a Value`, as the lifetime requirement means it can't
refer to local variables
2. _shouldn't_ be `Cow<'a, Value>`, as once it becomes an owned value,
it can't be borrowed ever again, as `current` is derived from its
previous value in further iterations. So once it's owned, it can't be
indexed by reference, leading to more clones
We need `current` to have _two_ possible lifetimes
1. `'out`: references derived from `&self`
2. `'local`: references derived from an owned value stored in a local
variable
```rust
enum MultiLife<'out, 'local, T>
where
'out: 'local,
T: ?Sized,
{
Out(&'out T),
Local(&'local T),
}
```
With `current: MultiLife<'out, '_, Value>`, we can traverse values with
minimal clones, and we can transform it to `Cow<'out, Value>` easily
(`MultiLife::Out -> Cow::Borrowed, MultiLife::Local -> Cow::Owned`) to
return it

- A few days back I've got this idea regarding recalculus of width.
Now it calculates step by step.
So 1 loop over all data was removed.
All though there's full recalculation in case of `header_on_border`
😞 (can be fixed..... but I decided to be short)
In perfect world it also shall be refactored ......
- Also have done small refactoring to switch build table from
`Vec<Vec<_>>>` to table itself. To hide internals (kind of still there's
things which I don't like).
It touched the `--expand` algorithm lightly you can see the tests
changes.
- And when doing that noticed one more opportunity, to remove HashMap
usage and directly use `tabled::ColoredConfig`. Which reduces copy
operations and allocations.
- And fixed a small issue where trailing column being using deleted
column styles.
To conclude optimizations;
I did small testing and it's not slower.
But I didn't get the faster results either.
But I believe it must be faster well in all cases, I think maybe bigger
tables must be tested.
Maybe someone could have a few runs to compare performance.

# Description
When first using `http get`, I was confused that all the examples used a
list for headers, leading me to believe this was the only way, and it
seemed a little weird having records in the language. Then, I found out
that you can indeed use record, so I changed the example to show this
behavior in a way users can find. There still is another examples that
uses a list so there should be no problem there.

This PR seeks to add a quality-of-life feature that enables date and
datetime parsing of strings in `polars into-df`, `polars into-lazy`, and
`polars open`, and avoid the more verbose method of casting each column
into date/datetime. Currently, setting the schema to `date` on a `str`
column would silently error as a null column. See a comparison of the
current and proposed implementations.
The proposed implementation assumes a date format "%Y-%m-%d" and a
datetime format of "%Y-%m-%d %H:%M:%S" for naive datetimes and "%Y-%m-%d
%H:%M:%S%:z" for timezone-aware datetimes. Other formats must be
specified via parsing through `polars as-date` and `polars as-datetime`.

# Description
This PR implements an experimental inter-job communication model,
through direct message passing, aka "mail"ing or "dm"ing:
- `job send <id>`: Sends a message the job with the given id, the root
job has id 0. Messages are stored in the recipient's "mailbox"
- `job recv`: Returns a stored message, blocks if the mailbox is empty
- `job flush`: Clear all messages from mailbox
Additionally, messages can be sent with a numeric tag, which can then be
filtered with `mail recv --tag`.
This is useful for spawning jobs and receiving messages specifically
from those jobs.
This PR is mostly a proof of concept for how inter-job communication
could look like, so people can provide feedback and suggestions
Closes #15199
May close#15220 since now jobs can access their own id.
# User-Facing Changes
Adds, `job id`, `job send`, `job recv` and `job flush` commands.
# Tests + Formatting
[X] TODO: Implement tests
[X] Consider rewriting some of the job-related tests to use this, to
make them a bit less fragile.

# Description
Fixes: #15510
I think it's introduced by #14653, which changes `and/or` to `match`
expression.
After looking into `compile_match`, it's important to collect the value
before matching this.
```rust
// Important to collect it first
builder.push(Instruction::Collect { src_dst: match_reg }.into_spanned(match_expr.span))?;
```
This pr is going to apply the logic while compiling `and/or` operation.
# User-Facing Changes
The following will raise a reasonable error:
```nushell
> (nu --testbin cococo false) and true
Error: nu:🐚:operator_unsupported_type
× The 'and' operator does not work on values of type 'string'.
╭─[entry #7:1:2]
1 │ (nu --testbin cococo false) and true
· ─┬ ─┬─
· │ ╰── does not support 'string'
· ╰── string
╰────
```
# Tests + Formatting
Added 1 test.
# After Submitting
Maybe need to update doc

A friend of mine started using nushell on Windows and wondered why the
`cat` command wasn't available. I answered to him, that he can use `help
-f` or F1 to find the command but then we both realized that neither
`cat` nor `Get-Command` were part of `open`'s search terms. So I added
them.

The current implementation improperly inverts the conversion from
nanoseconds to the specified time units, resulting in nonsensical
Datetime and Duration parsing and integer overflows when the specified
time unit is not nanoseconds. This PR seeks to correct this conversion
by changing the multiplication to an integer division. Below are
examples highlighting the current and proposed implementations.
## Current Implementation
Specifying a different time unit incorrectly changes the returned value.
```nushell
> [[a]; [2024-04-01]] | polars into-df --schema {a: "datetime<ns,UTC>"}
╭───┬───────────────────────╮
│ # │ a │
├───┼───────────────────────┤
│ 0 │ 04/01/2024 12:00:00AM │
> [[a]; [2024-04-01]] | polars into-df --schema {a: "datetime<ms,UTC>"}
╭───┬───────────────────────╮
│ # │ a │
├───┼───────────────────────┤
│ 0 │ 06/27/2035 11:22:33PM │ <-- changing the time unit should not change the actual value
> [[a]; [1day]] | polars into-df --schema {a: "duration<ns>"}
╭───┬────────────────╮
│ # │ a │
├───┼────────────────┤
│ 0 │ 86400000000000 │
╰───┴────────────────╯
> [[a]; [1day]] | polars into-df --schema {a: "duration<ms>"}
╭───┬──────────────────────╮
│ # │ a │
├───┼──────────────────────┤
│ 0 │ -5833720368547758080 │ <-- i64 overflow
╰───┴──────────────────────╯
```
## Proposed Implementation
```nushell
> [[a]; [2024-04-01]] | polars into-df --schema {a: "datetime<ns,UTC>"}
╭───┬───────────────────────╮
│ # │ a │

# User-Facing Changes

No user-facing breaking change.
Developer breaking change: to mitigate the silent overflow in
nanoseconds conversion functions `nanos_from_timeunit` and
`nanos_to_timeunit` (new), the function signatures were changed from
`i64` to `Result<i64, ShellError>`.

No additional examples were added, but I'd be happy to add a few if
needed. The covering tests just didn't fit well into any examples.
