Document indexer test fixture

A small line-oriented test language (.idx), unrelated to any framework: def key, ref key, alias prefix# target# and symbols prefix. References also produce gutter markers. symbols uses host-supplied UTF-16 syntax ranges. invalid key deliberately returns an out-of-bounds range.

Used by cargo test -p ide-host --test plugin_indexing to exercise the optional WIT export, lifecycle invalidation, permissions, per-window isolation, candidate selection and warm memory-only lookups. It is not a marketplace plugin.
