Prerequisite: call `fetch_data` for the symbol first so the OHLCV cache exists.
Long-running: up to a 300-second timeout; reports progress to capable clients.

save defaults to true so the result JSON is persisted (with `saved_path` in the
response) and can be fed to `apply_optimization`; pass save=false to skip saving.
Long-running: up to a 600-second timeout; reports progress to capable clients.

windows defaults to 5, metric to sharpe_ratio. Run it after run_optimize to compare
in-sample vs out-of-sample behaviour (the optimize_and_verify workflow).
Long-running: up to a 600-second timeout; reports progress to capable clients.

Prerequisite: a saved result (run_backtest/run_optimize with save) — result_id =
strategy_id or run_id. simulations defaults to 1000. Returns ruin probability, equity
percentiles, and drawdown distribution for risk assessment.
Long-running: reports progress to capable clients; has an execution timeout.

period is e.g. 1y / 5y / 6m / 30d / max (defaults to 1y). Returns {symbol, period,
output}. The CLI has no --start/--end, so only period is exposed. Run this before
run_backtest. Reports progress to capable clients; has an execution timeout.

Pass the full strategy-definition JSON as a string; it is validated as a JSON object
and written to a temp file before `strategy save`. Returns {output}. A registered
strategy is the prerequisite for run_backtest/run_optimize. Reports progress to
capable clients; has an execution timeout.

Read-only triage: returns {binary_found, version, authenticated, plan, doctor, error}.
Never fails when the binary is missing — returns binary_found=false instead.

Prerequisite: run_optimize(save=true) — result_file is its `saved_path`. Runs
non-interactively (--yes). Returns {result_file, strategy_id, output}. Follow up by
generating Pine Script for `<strategy_id>_optimized`. Reports progress to capable
clients; has an execution timeout.

Optional `goal` filters by exploration goal; defaults to the "default" goal.

`indicator` is the indicator name (e.g. RSI, MACD). This is metadata only — the CLI
has no compute-over-symbol command — so it does not run a calculation on price data.
