inputExamples

Few-shot example inputs encoded as JSON strings. Mirrors v6's tool.inputExamples (per historical parity gap #19). Disproportionate quality lift on small models — Gemma 4 E2B's tool-call accuracy notably improves with 2-3 in-tool examples. ToolSet.descriptors inlines these into the description as Example: <json> so every provider sees them (most don't expose a separate examples field).
