Custom command attributes (#14906)
# Description
Add custom command attributes.

- Attributes are placed before a command definition and start with a `@`
character.
- Attribute invocations consist of const command call. The command's
name must start with "attr ", but this prefix is not used in the
invocation.
- A command named `attr example` is invoked as an attribute as
`@example`
-   Several built-in attribute commands are provided as part of this PR
    -   `attr example`: Attaches an example to the commands help text
        ```nushell
        # Double numbers
        @example "double an int"  { 5 | double }   --result 10
        @example "double a float" { 0.5 | double } --result 1.0
        def double []: [number -> number] {
            $in * 2
        }
        ```
    -   `attr search-terms`: Adds search terms to a command
    -   ~`attr env`: Equivalent to using `def --env`~
- ~`attr wrapped`: Equivalent to using `def --wrapped`~ shelved for
later discussion
    -   several testing related attributes in `std/testing`
- If an attribute has no internal/special purpose, it's stored as
command metadata that can be obtained with `scope commands`.
- This allows having attributes like `@test` which can be used by test
runners.
-   Used the `@example` attribute for `std` examples.
-   Updated the std tests and test runner to use `@test` attributes
-   Added completions for attributes

# User-Facing Changes
Users can add examples to their own command definitions, and add other
arbitrary attributes.

# Tests + Formatting

- 🟢 toolkit fmt
- 🟢 toolkit clippy
- 🟢 toolkit test
- 🟢 toolkit test stdlib

# After Submitting
- Add documentation about the attribute syntax and built-in attributes
- `help attributes`

fix multiline strings in NDNUON (#14519)
- should close https://github.com/nushell/nushell/issues/14517

# Description
this will change `to ndnuon` so that newlines are encoded as a literal
`\n` which `from ndnuon` is already able to handle

# User-Facing Changes
users should be able to encode multiline strings in NDNUON

# Tests + Formatting
new tests have been added:
- they don't pass on the first commit
- they do pass with the fix

add from ndnuon and to ndnuon to stdlib (#14334)
# Description
i was playing with the NDNUON format and using local definitions of
`from ndnuon` and `to ndnuon` but then i thought they could live in the
standard library next to `from ndjson` and `to ndjson` 😋

# User-Facing Changes
users can now add the following to their configs and get NDNUON ready to
go
```nushell
use std formats ["from ndnuon" "to ndnuon"]
```

# Tests + Formatting
i did simply mimic the tests for `from ndjson` and `to ndjson`, i hope
it's fine since the recent big change to the standard library

Fix dirs removal warning (#14029)
# Description

* Primary purpose is to fix an issue with a missing escaped opening
parenthesis in the warning message when running an old `dirs` alias.
This was creating an error condition from improper interpolation.

Also

* Incorporates #13842 feedback from @kubouch by renaming `std/lib` to
`std/util`
* Removes duplication of code in `export-env`
* Renames submodule exports to `std/<submodule>` rather than
`./<submodule>` - No user-facing change other than `view files` appears
"prettier".
* In #13842, I converted the test cases to use `use std/<module>`
syntax. Previously, the tests were (effectively) using `use std *` (due
to pre-existing bugs, now fixed).

So "before", we only had test coverage on `use std *`, and "after" we
only had test coverage on `use std/<module>`. I've started adding test
cases so that we have coverage on *both* scenarios going forward.

For now, `formats` and `util` have been updated with tests for both
scenarios. I'll continue adding the others in future PRs.

# User-Facing Changes

No user-facing changes - Bug fix, refactor, and test cases only

# Tests + Formatting

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

Still working on updating the Doc. I ran into the `dirs` issue while
writing it and rabbit-trailed to fix it in this PR.
