/**
 * kilo capability UPGRADES — ADR-1239 Phase D / #2093 (EoS/kilo).
 *
 * Drives the user-reachable surface (spawned `bin/install.js` via
 * `runMinimalInstall`) plus targeted unit coverage to prove the four real
 * upgrades Kilo contributes as part of the imperative-adapter migration:
 *
 *   UPGRADE 1 — native hook-bus plugin: `.kilo/plugins/gsd-core.js`, a
 *   byte-identical copy of `.opencode/plugins/gsd-core.js` (Kilo is an
 *   OpenCode fork sharing the same plugin/extension event bus).
 *
 *   UPGRADE 2 — active-model routing: `convertClaudeToKiloFrontmatter` now
 *   emits a `model:` field from the resolved model override instead of
 *   always stripping it (mirrors the OpenCode upgrade, #2256).
 *
 *   UPGRADE 3 — MCP companion documented + reachable: `docs/how-to/connect-gsd-mcp-server.md`
 *   covers Kilo's `mcp`-keyed config (not `mcpServers`), and the companion the
 *   doc points at (`bin/gsd-mcp-server.js`) is proven live by spawning it and
 *   performing a real initialize + tools/list handshake (AC4: "test: connect
 *   and list tools") — mirrors tests/gsd-mcp-server-bin.test.cjs exactly.
 *
 *   UPGRADE 4 — named subagent dispatch: GSD's specialist agents install as
 *   `<configDir>/agents/gsd-*.md` with `mode: subagent` + a `permission:`
 *   block — the slug Kilo's Task tool dispatches by.
