magpie/internal/gui/tests/project-remove-keep.test.cjs

// Run with Node's test runner and Playwright on the module path; see README.md.
// #514: removing a project took away every skill and MCP server magpie had
// put in it, so a project given some once had to stay in magpie for good.
// The Remove dialog now has "Keep its skills and MCP servers": checked, its
// text says what stays, and Remove posts projects/remove with keep, the
// status saying they were kept; unchecked, it posts as before. A project
// magpie put nothing in has no such box. Pressing the box scrolls nothing;
// in English and Chinese. No backend: the API is faked here.
