# Description
This PR adds those markdown doc strings (previously only available via
hover) to completion items:
<img width="676" alt="image"
src="https://github.com/user-attachments/assets/58c44d7d-4b49-4955-b3f0-fa7a727a8bc0"
/>
It also refactors a bit, primarily to prevent namespace pollution.

avoid unnecessary parsing, this PR caches the `StateDelta` to the

`tower-lsp` seems not well-maintained, I ended up with a dedicated
thread for heavy computing and message passing to cancel it on any new
request.
During the progress, interrupting with edits or new requests.

Goto references are still blocking, with a hard timeout of 5 seconds.
Only locations found within the time limit are returned. Technically,
reference requests allow for responses with partial results, which means
instant responsiveness. However, the `lsp_types` crate hasn’t enabled
this. I believe I can still enable it with some JSON manipulation, but
I’ll leave it for future work.

Caveats:
1. Module reference/rename is not supported yet
2. names in `use` command should also be renamed, which is not handled
now
3. workspace wide actions can be time-consuming, as it requires parsing
of all `**/*.nu` files in the workspace (if its text contains the name).
Added a progress bar for such requests.
4. In case these requests are triggered accidentally in a root folder
with a large depth, I hard-coded the max depth to search to 5 right now.

This PR adds inlay hints of variable types and parameter names to
lsp-server
<img width="547" alt="image"
src="https://github.com/user-attachments/assets/07a0dd84-5ecc-47df-a8a7-732631715662"
/>
Some design choices I made:
* for composite types like `record<foo: <record ...>>`, only a short
name displayed. Full signature already available through `hover`
* only parameter names of user defined commands are returned, feels too
much distraction if enabled for all builtins
* some information are lost in flattened expressions, so I implemented
my AST traversing functions, which may seem unnecessary, but I can't
find alternatives from the existing code.
* another minor change: added a line separator to current hover markdown
message.

This PR replaces `ropey` with `lsp-textdocument` for easier utf16
position handling.
As a side effect, if fixes the following crashing bug:
1. create a `foo.nu` file with errors in it
2. in `bar.nu`, add code `use foo.nu *`
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* <s>Diagnostics are now triggered only with document open/save, that's
my personal preference. Changing back to previous behavior is easy if
you guys have other concerns.</s>
* UTF-8 position encoding is not supported by lsp-textdocument, but
that's not an issue, since the previous utf-8 ropey implementation is
buggy when used in real scenarios in a text editor.

# Description
Refactors the code in `nu-cli`, `main.rs`, `run.rs`, and few others.
Namely, I added `EngineState::generate_nu_constant` function to
eliminate some duplicate code. Otherwise, I changed a bunch of areas to
return errors instead of calling `std::process::exit`.
# User-Facing Changes
Should be none.
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
ShellError, Signature, Span, Type, Value,
};
```
This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
ast::{Call, CellPath},
engine::{Command, EngineState, Stack},
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```
This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.
# Description
The code that converts Nushell's span into LSP line and character
indices accidentally treated the span as character indices while they
are byte indices. Fixes#11522.
# User-Facing Changes
None, just a bugfix.
