obleth-gateway v0.9.1

Benchmarks report tokens-per-second, and benchmark traffic finally stays out of your real usage numbers.

• Tokens-per-second across the benchmark suite. Every concurrency step now reports aggregate output tok/s and per-stream decode rate (p50/p10) — in the obench CLI summary, the live TUI, the capacity scorecard, and Charo's inline benchmark card.
• Benchmark and test traffic no longer pollutes usage stats. Charo's model-test console and in-dashboard benchmarks reach the gateway through a reserved internal identity, which is now marked synthetic — so its requests are tagged as benchmark traffic and excluded by default from the overview's request, token, and tokens-per-second figures. Previously a single capacity run could bury a model's real numbers under thousands of synthetic requests. Existing pre-upgrade rows age out of the rolling window on their own; internal traffic stays viewable on demand.
• Charo hides models' hidden reasoning. Chain-of-thought that some models emit inline (<think>…</think>) is now stripped from Charo's answers and from the transcript sent back upstream, so you see the reply and its tool cards, not the scratchpad.
• The chat panel, refined. Assistant replies render as clean chat bubbles, the mascot imagery is retired for a tighter layout, and the typing indicator sits in-bubble so a pending reply never reads as dead air.
