feat(vscode-extension): add package-vsix script and local vsce devDependency

Collapses the multi-step VSIX build into a single `pnpm package-vsix`
command and removes the requirement for a global `@vscode/vsce` install.
Also adds a `repository` field to the extension package.json (required by
vsce to resolve relative README links) and gitignores *.vsix artefacts.
