Feature request: Add "Run Current Cell and Below" command/link in Quarto VS Code notebooks

[lucazav]

Description
When working with Quarto notebooks in VS Code, each code cell currently shows links such as:

• Run Cell
• Run Next Cell
• Run Above

However, there is no option to run the current cell and all cells below, which is a very common workflow in Jupyter-style environments.

This capability is especially useful when:

• Re-running an entire analysis pipeline after modifying a cell in the middle of the notebook
• Avoiding manual multi-cell execution or restarting the kernel
• Working with long notebooks where execution order matters

Adding a "Run Current and Below" (or similar) command would significantly improve productivity and align the experience with other notebook ecosystems.

Proposed Feature
Add a new command/link in the cell toolbar:

• Run Current and Below

Optionally also expose it via:

• Command Palette
• Keyboard shortcut

Expected Behavior
From any cell, the user can execute that cell and all subsequent cells in top-to-bottom order.

Actual Behavior
Only the following options are available:

• Run Cell
• Run Next Cell
• Run Above

No built-in way to run current cell plus all following cells.

Why this matters
Quarto notebooks are often used for reproducible data science and ML workflows. Missing this execution mode makes iterative development slower and increases friction compared to Jupyter Notebooks.

Environment

• VS Code: (add your version)
• Quarto extension: (add your version)
• OS: Windows 10/11 (or your OS)

Additional Notes
If there is already an internal command that supports this behavior, exposing it in the UI would also be sufficient.
