normalizeEnvelopeArgs

The parent LLM may emit envelope-tool arguments in four shapes (observed in the spike across gpt-5-mini and gpt-5): the canonical {envelopes: [...]}, a singular typo {envelope: [...]}, positional keys {0: env, 1: env, ...} when the model treats the args as the array, or a flat single envelope. This pure function maps all four into a canonical envelope list.

Strict-mode tool binding (OpenAI) should eliminate the non-canonical shapes in production, but the normalizer is the safety net.
