query_symbols returns exact Kotlin symbols. A result can carry a kind,
name, source location, signature, and an opaque ref. The
query item schema defines the full shape.
Pass the returned exact
ref unchanged to later query or source reads. A
matching name, file path, or reconstructed token does not prove exact identity.
The symbol query example works without knowing a project-specific
name. Keep the result’s coverage with any symbol you report.
