[Spec 0602] Add VS Code extension scaffold to monorepo

Copy extension scaffold into packages/codev-vscode/ as a workspace
member. Add root .vscode/ with launch, tasks, settings, and
recommended extensions for F5 debugging. Remove internal .vscode/
from extension package. Update .gitignore for extension build output.
