When GStreamer pipeline graphs contain references to other pipeline dot files,
users should be able to navigate between related pipeline views by clicking
on these references. This enables exploring complex pipeline hierarchies
where one pipeline references sub-pipelines.
The implementation detects text elements containing pipeline-dot references,
styles them as web links, and handles click events to navigate to the
referenced pipeline while preserving existing text selection and drag
functionality for other elements.

Enable text selection on SVG text elements by changing CSS user-select
properties from 'none' to 'text' and cursor from 'default' to 'text'.
Add JavaScript event handling to intercept mousedown events on text
elements, preventing dragscroll interference while allowing normal text
selection. This preserves the existing drag-to-pan functionality for
non-text areas while making text elements selectable and copyable.

The fact that static-files followed the (nondeterministic) file system
order is likely what caused the dots-viewer executable not to be binary
reproducible. Enabling this feature that was added upstream should fix
it.

Otherwise if GStreamer is checked out inside a directory that
has a `Cargo.toml` file, building fails with:
```
error: current package believes it's in a workspace when it's not:
current rust-project/gstreamer/subprojects/gst-devtools/dots-viewer/Cargo.toml
workspace rust-project/Cargo.toml
This may be fixable by adding `gstreamer/subprojects/gst-devtools/dots-viewer`
to the `workspace.members` array of the manifest located at: rust-project/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude`
array, or add an empty `[workspace]` table to the package's manifest.
```

Add a button in the web interface to trigger pipeline dumps via websocket,
replacing the need to manually send SIGUSR1 to the process. Also set up
the pipeline-snapshot tracer with the proper websocket URL by default.
