Fix related to #26906.
Currently, if a file is removed, no event is emitted because the file
path no longer exists. As a result, [this
check](12b377247b/runtime/ops/fs_events.rs (L149))
returns false.
With this PR, an additional check is introduced to verify if the file
exists. If the file does not exist, a custom "remove" event is emitted.
This change is necessary because, based on tests conducted on macOS and
Linux (Ubuntu 24.04.1 LTS), Linux emits a "rename" event instead of a
"remove" event when a file is deleted. Introducing a dedicated "remove"
event ensures consistent and clearer behavior across platforms.
This commit adds `Deno.jupyter.image` API to display PNG and JPG images:
```
const data = Deno.readFileSync("./my-image.jpg");
Deno.jupyter.image(data);
Deno.jupyter.image("./my-image.jpg");
```
This PR fixes #24453, by introducing a ctime (using ctime for UNIX and
ChangeTime for Windows) to Deno.stats.

Fixes https://github.com/denoland/deno/issues/23508
`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

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.

This fixes the fast path for `readableStreamCollectIntoUint8Array` to
only trigger if the readable stream has not yet been disturbed -
because otherwise we may not be able to close it if the
read errors.
This commit fixes the error format when the cause is assigned
separately, ensuring that the cause is only printed once instead of
twice.
The fix addresses issue
[#21651](https://github.com/denoland/deno/issues/21651).
This commit removes all occurrences of `--unstable` flag
from all the tests that are run in CI.
Turns out none of the tests actually required that flag
anymore.
