// scripts/qa-cdp-shoot-mcp-surface.mjs — MCP frontend delivery batch selfies
// (task #49, 2026-07-17). Shoots the three P0 tickets from the audit at
// docs/plugin-mcp-audit.md §4:
//
//   01-mcp-config-card             — Plugins → Installed, dsh-mcp-client row
//                                    inline config card with transport radio
//                                    + serverName + command/args/env
//                                    (audit §2 row 1 & 3 gap: "装了没入口").
//   02-mcp-config-card-http        — same card, streamable-http transport;
//                                    the fields swap (url + headers) so the
//                                    UX proves the segmented control works.
//   03-mcp-tool-chip-in-trace      — Trace-detail Attributes tab, tool_use
//                                    row shows "mcp · <server>" chip and
//                                    the Runtime group carries mcp.server.
//                                    (audit §2 row 4 gap: "trace 归属").
//   04-market-import-workspace     — Plugins → Browse, Import from… panel
//                                    with workspace-pkg shape filled in.
//   05-market-import-path          — same panel, local-path shape selected.
//   06-market-import-git-disabled  — same panel, git URL tab shows the
//                                    coming-soon note honestly.
