Models like MiniMax emit inline <think>...</think> reasoning blocks in their content field. The CLI already suppresses these via a state machine in _stream_delta, but the gateway's GatewayStreamConsumer had no equivalent filtering — raw think blocks were streamed directly to Discord/Telegram/Slack. The fix adds a _filter_and_accumulate() method that mirrors the CLI's approach: a state machine tracks whether we're inside a reasoning block and silently discards the content. Includes the same block-boundary check (tag must appear at line start or after whitespace-only prefix) to avoid false positives when models mention <think> in prose. Handles all tag variants: <think>, <thinking>, <THINKING>, <thought>, <reasoning>, <REASONING_SCRATCHPAD>. Also handles edge cases: - Tags split across streaming deltas (partial tag buffering) - Unclosed blocks (content suppressed until stream ends) - Multiple consecutive blocks - _flush_think_buffer on stream end for held-back partial tags Adds 22 unit tests + 1 integration test covering all scenarios.
