Real-Answer Benchmark feature — Press Ctrl+A to run a live completion benchmark on the currently selected model. Measures actual wall-clock response time and tokens-per-second (TPS) with a real chat completion request ("Why is the sky blue? Answer in exactly one short sentence."). Results appear in the new Answer Speed column as 4.3s / 13 TPS.
New Answer Speed column in the TUI table, positioned after the Uptime column. Defaults to —, shows a green spinner while benchmarking, and displays compact error codes (ERR, TIMEOUT, 401, 429) on failure.
New module src/benchmark.js with lightweight, native Node.js benchmark logic:
- benchmarkModel({ apiKey, modelId, providerKey, url }) — sends one completion, measures time, parses usage.completion_tokens with a Math.ceil(outputText.length / 4) fallback clearly labeled as an estimate.
- Guards against division-by-zero and unsupported providers (rovo, gemini, opencode-zen return UNSUPPORTED).
- Respects existing API key handling and fails gracefully on missing credentials, rate limits, or timeouts.
Benchmark state stored in TUI state keyed by ${providerKey}/${modelId}, so results survive re-renders and table refreshes.
Ctrl+A documented in the Help overlay (I key).

Responsive column breakpoints adjusted to accommodate the new Answer Speed column (14 cols). Progressive hiding order: Rank → Answer Speed → Up% → Tier → Stability. Compact mode still active at ~163+ cols.
Removed the startup Shell Environment popup — The modal that asked existing users whether to export API keys to shell on every launch has been eliminated. It was intrusive and re-appeared even after being skipped.
Shell Environment setup is now on-demand via Settings (P key). The "Shell Env Export" row shows:
- 🔘 Not configured — Enter to set up for users who never configured it (previously shown the popup)
- ✅ Enabled when active
- ❌ Disabled when explicitly turned off
New users who add their first API key still get shell env enabled automatically (zero-friction default). Existing users can press Enter on the Settings row to enable it at any time.
