mohdel v0.103.0

Fixed

• Suffix stripped from envelope.model when explicit outputEffort
  wins. Previously the :effort shortcut leaked into
  gen_ai.request.model, the scoped logger, and the trace cache key.
• thinkingTokens no longer reported as 0 when an Anthropic call
  emits redacted_thinking blocks (claude-opus-4-7 default). The
  adapter falls back to estimating thinking from the gap between
  Anthropic's usage.output_tokens and the visible streamed content
  (text + tool input_json_delta). Cost unchanged — the
  thinkingPrice == outputPrice invariant means redistribution only.
