This commit adds better handling for terminal errors when
`window` global is used. This global is removed in Deno 2,
and while we have lints to help with that, an information and
hints are helpful to guide users to working code.

`width` and `height` are required to configure the wgpu surface because
Deno is headless and depends on user to create a window. The options
were non-standard extension of `GPUCanvasConfiguration#configure`.
This PR adds a required options parameter with the `width` and `height`
options to `Deno.UnsafeWindowSurface` constructor.
```typescript
// Old, non-standard extension of GPUCanvasConfiguration
const surface = new Deno.UnsafeWindowSurface("x11", displayHandle, windowHandle);
const context = surface.getContext();
context.configure({ width: 600, height: 800, /* ... */ });
```
```typescript
// New
const surface = new Deno.UnsafeWindowSurface({
system: "x11",
windowHandle,
displayHandle,
width: 600,
height: 800,
});
const context = surface.getContext();
context.configure({ /* ... */ });
```
This PR optimizes the case when `performance.measure()` needs to find
the startMark by name. It is a simple change on `findMostRecent` fn to
avoiding copying and reversing the complete entries list.
Adds minor missing tests for:
- `clearMarks()`, general
- `clearMeasures()`, general
- `measure()`, case when the startMarks name exists more than once

Fixes a regression where we were ignoring `--node-modules-dir` if there
was no value passed with it. We should instead default to "auto", to
maintain compat with deno 1
Fixes rsbuild running in deno.
You can look at the test to see what was failing, the gist is that we
were trying to statically analyze the re-exports of a CJS script, and if
we couldn't find the source for the re-exported file we would fail.
Instead, we should just treat these as if they were too dynamic to
analyze, and let it fail (or succeed) at runtime. This aligns with
node's behavior.
This commit fixes issues with the pseudo test file generation logic,
namely:
- `export`s declared in snippets
- auto import insertion for `default export`
## Case 1: `export`s declared in snippets
In the previous implementation, `export`s declared in snippets were
moved to the top level of the module in the generated pseudo test file.
This is required because `export` must be at the top level.
This becomes a problem if such a `export` has a body, containing a
reference to a local variable. Suppose we extract this snippet from
JSDoc:
```ts
const logger = createLogger("my-awesome-module");
export function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
```
This gets converted into the following invalid code (note that `export
function sum` is moved to the top level, but its body references
`logger` variable which can't be referenced from here):
```ts
export function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
Deno.test("./base.ts$1-7.ts", async () => {
const logger = createLogger("my-awesome-module");
});
```
To resolve this issue, this commit adds a logic to remove the `export`
keyword, allowing the exported items to stay in the `Deno.test` block
scope, like so:
```ts
Deno.test("./base.ts$1-7.ts", async () => {
const logger = createLogger("my-awesome-module");
function sum(a: number, b: number): number {
logger.debug("sum called");
return a + b;
}
});
```
## Case 2: default export
Previously `default export foo` was not captured by the export
collector, so auto import insertion didn't work for this case. To put it
concretely, the following code snippet didn't work when run with `deno
test --doc` because `import foo from "file:///path/to/mod.ts"` didn't
get inserted automatically:
```ts
/**
* ```ts
* console.log(foo);
* ```
*
* @module
*/
const foo = 42;
export default foo;
```
This commit fixes this issue and the above example works fine.

Fixes #25718
Aligns the error messages in the ext/http and a few messages in the
ext/fetch folder to be in-line with the Deno style guide.
This change-set also removes some unnecessary checks in the 00_serve.ts.
These options were recently removed, so it doesn't make sense to check
for them anymore.
