adk-guardrail 0.7.0

//! # adk-guardrail
//!
//! Guardrails framework for validating agent inputs and outputs.
//!
//! ## Overview
//!
//! Guardrails run in parallel with agent execution and can:
//! - Block harmful or off-topic content
//! - Enforce output schemas
//! - Redact PII (emails, phones, SSNs)
//! - Limit costs and token usage
//!
//! ## Quick Start
//!
//! ```rust,ignore
//! use adk_guardrail::{GuardrailSet, ContentFilter, PiiRedactor};
//!
//! let input_guardrails = GuardrailSet::new()
//!     .with(ContentFilter::harmful_content())
//!     .with(PiiRedactor::new());
//!
//! let agent = LlmAgentBuilder::new("assistant")
//!     .input_guardrails(input_guardrails)
//!     .build()?;
//! ```
