pub fn validate_context_path(value: &str) -> Result<(), AppError>Expand description
Validate a context path: non-empty, ≤ MAX_CONTEXT_DEPTH segments, every
segment a valid identifier, and no empty / leading / trailing / doubled
separators.
Thin wrapper over vta_sdk::context_path::validate_context_path mapping
the SDK error onto AppError::Validation (message preserved verbatim).
