/**
 * CommonJS marker ownership — regression coverage for #2544.
 *
 * `installSharedHooksBundle` used to write `{"type":"commonjs"}` over
 * `<configRoot>/package.json` unconditionally — no existence check, no merge,
 * no backup. On OpenCode that file is documented, user-writable
 * territory (it is where local-plugin npm dependencies are declared), so every
 * install and every `/msd-update` destroyed the user's `name`, `type`,
 * `dependencies`, and `scripts`.
 *
 * The uninstall path had always read the file first and unlinked it only on an
 * exact content match. The defect was that asymmetry: the discipline existed,
 * it just was not applied on the write side.
 *
 * The fix moves the marker into the directories MSD actually fills with its own
 * `.js` files — `hooks/` and the `nativePlugin.dir` — and routes install and
 * uninstall through one shared ownership predicate. These tests pin both
 * halves: the config root is never written, and a user-authored package.json is
 * never overwritten even where MSD does write.
 *
 * Coverage maps to the issue's acceptance criteria:
 *   AC1 — a user-authored config-root package.json survives a fresh install
 *   AC2 — it survives a second install (the `/msd-update` re-install path)
 *   AC3 — MSD's staged .js files still resolve as CommonJS
 *   AC4 — uninstall removes only markers MSD wrote
