feat(vscode-web): add workspace file support

[blink-so]

Summary

Adds support for opening .code-workspace files directly in the VS Code Web module, resolving the issue where workspace files would open briefly then refresh.

Changes

• New workspace variable: Allows specifying a path to a .code-workspace file
• Mutual exclusion validation: Prevents using both folder and workspace parameters simultaneously
• Enhanced URL generation: Properly constructs VS Code web URLs with ?workspace= parameter
• Updated run.sh script: Passes workspace files as arguments to code-server serve-local
• Documentation: Added example usage in README
• Version bump: Updated to 1.3.2

Usage

module "vscode-web" {
  agent_id       = coder_agent.example.id
  workspace      = "/home/coder/project.code-workspace"
  accept_license = true
}

Technical Details

This implementation leverages VS Code web's native ?workspace= URL parameter support, which properly handles .code-workspace files without the refresh/redirect issues seen with direct file opening attempts.

Testing

• Terraform formatting applied
• Lifecycle preconditions validate mutual exclusion
• Backward compatibility maintained for existing folder parameter
• Documentation updated with examples
