feat: multi-provider model benchmark (boil the ocean)
Adds the full spec Codex asked for: real provider adapters with auth
detection, normalized RunResult, pricing tables, tool compatibility
maps, parallel execution with error isolation, and table/JSON/markdown
output. Judge stays on Anthropic SDK as the single stable source of
quality scoring, gated behind --judge.

Codex flagged the original plan as massively under-scoped — the
existing runner is Claude-only and the judge is Anthropic-only. You
can't benchmark GPT or Gemini without real provider infrastructure.
This commit ships it.

New architecture:

  test/helpers/providers/types.ts       ProviderAdapter interface
  test/helpers/providers/claude.ts      wraps `claude -p --output-format json`
  test/helpers/providers/gpt.ts         wraps `codex exec --json`
  test/helpers/providers/gemini.ts      wraps `gemini -p --output-format stream-json --yolo`
  test/helpers/pricing.ts               per-model USD cost tables (quarterly)
  test/helpers/tool-map.ts              which tools each CLI exposes
  test/helpers/benchmark-runner.ts      orchestrator (Promise.allSettled)
  test/helpers/benchmark-judge.ts       Anthropic SDK quality scorer
  bin/gstack-model-benchmark            CLI entry
  test/benchmark-runner.test.ts         9 unit tests (cost math, formatters, tool-map)

Per-provider error isolation:
  - auth → record reason, don't abort batch
  - timeout → record reason, don't abort batch
  - rate_limit → record reason, don't abort batch
  - binary_missing → record in available() check, skip if --skip-unavailable

Pricing correction: cached input tokens are disjoint from uncached
input tokens (Anthropic/OpenAI report them separately). Original
math subtracted them, producing negative costs. Now adds cached at
the 10% discount alongside the full uncached input cost.

CLI:
  gstack-model-benchmark --prompt "..." --models claude,gpt,gemini
  gstack-model-benchmark ./prompt.txt --output json --judge
  gstack-model-benchmark ./prompt.txt --models claude --timeout-ms 60000

Output formats: table (default), json, markdown. Each shows model,
latency, in→out tokens, cost, quality (when --judge used), tool calls,
and any errors.

Known limitations for v1:
- Claude adapter approximates toolCalls as num_turns (stream-json
  would give exact counts; v2 can upgrade).
- Live E2E tests (test/providers.e2e.test.ts) not included — they
  require CI secrets for all three providers. Unit tests cover the
  shape and math.
- Provider CLIs sometimes return non-JSON error text to stdout; the
  parsers fall back to treating raw output as plain text in that case.
