Add “Compose Pull / Update All Images” command for Docker Compose projects

Problem

In VS Code Container Tools, I can run Compose Up and manage Compose groups, but I can’t find a command to refresh all images used by a compose file/group (equivalent to docker compose pull).

Why this matters

For multi-service stacks, updating all images is a frequent step before restart/deploy. Today this requires custom scripts/tasks outside the extension.

Requested feature

Add a command such as:

• Containers: Compose Pull
• Containers: Compose Update Images

Suggested behavior:

1. Detect compose files in workspace (or use selected compose group).
2. Pull all referenced images (optionally selected services).
3. Show progress/output in the extension terminal/output channel.
4. Offer optional follow-up actions (e.g., Compose Up / recreate changed services).

Environment

• Extension: ms-azuretools.vscode-containers
• OS: Windows
• Compose workflow: local multi-service stack

Start by locating the existing Compose Up command in the Container Tools extension and reading how it detects compose files or groups. Add a Compose Pull or equivalent command that pulls all referenced images, reports progress in the extension terminal or output channel, and supports the requested follow-up behavior where appropriate. Done means the command works for local multi-service Compose projects on Windows.
