🤖 refactor: update VS Code extension branding and marketplace publishing (#591)

## Summary

Updates the VS Code extension branding from "cmux" to "mux" and adds
automated marketplace publishing to the release workflow.

## Changes

### Branding Updates
- **Extension metadata**: Updated `name`, `displayName`, and
`description` in `package.json`
- **Command IDs**: Changed from `cmux.*` to `mux.*` (e.g.,
`mux.openWorkspace`)
- **User-facing strings**: Updated error messages, UI text, and console
logs
- **Domain reference**: Fixed to use correct live domain `cmux.io`
- **Keywords**: Updated marketplace keywords from "cmux" to "mux"

### GitHub Workflows
- **Artifact naming**: Changed from `cmux-*.vsix` to `mux-*.vsix` in
build and release workflows
- **Marketplace publishing**: Added automatic publishing to VS Code
marketplace on release
  - Requires `VSCE_PAT` secret to be set in repository settings
  - Only publishes if token is available (graceful degradation)
- **Workflow descriptions**: Updated composite action descriptions

## Marketplace Setup

To enable marketplace publishing, add the `VSCE_PAT` secret to
repository settings:

1. Create a Personal Access Token in Azure DevOps:
   - Go to https://dev.azure.com → Profile → Personal access tokens
   - Create token with **Marketplace (Manage)** scope
   - Set expiration (90 days recommended)

2. Add to GitHub repository:
   - Go to repository Settings → Secrets and variables → Actions
   - Create new secret: `VSCE_PAT` with your token value

The extension will automatically publish to the marketplace when a new
release is created.

## Testing

- ✅ Extension builds successfully with new naming
- ✅ GitHub workflows updated for new artifact names
- ✅ All user-facing text updated to "mux" branding
- ✅ Domain reference points to correct `cmux.io`
