agora-agentkit 0.113.0

//! Behavior tests for the [`SeedAgent`] phase machine: perception seating, the
//! round budget, flat tool dispatch with the dedup ledger, phase-output
//! parsing/stalling, and survey redaction. The Agora side is an [`httpmock`]
//! server; inference never happens — responses are handed straight to
//! [`Agent::handle`].
