Canonical normalized connector event schemas, authored as Harn type declarations. This is the SOURCE OF TRUTH for the Rust event-payload structs in crates/harn-vm/src/triggers/event/schemas_generated.rs, which are generated from these declarations by harn connector-schema-codegen.

It is intentionally NOT registered in STDLIB_SOURCES: it is a codegen input (like spec/openapi.yaml), not a module loaded into every program. Exposing it as an embedded string keeps the generator independent of the current working directory.
