Plan 0060 Tasks 4-5 (#106): wire `aura sweep|walkforward --real` end to end.
- A shared RealWindowGrammar accumulator holds the `--real <SYMBOL> [--from <ms>]
[--to <ms>]` grammar (flag-repeat strictness, empty-symbol + window-without-real
rejection) for both parsers, mirroring parse_real_args.
- parse_sweep_args grows the DataChoice 4th element; parse_walkforward_args is new
(no --strategy axis). The sweep + walkforward dispatch arms become rest-matched,
build the DataSource via from_choice (build-or-refuse on un-vetted symbol /
absent data), and run. USAGE documents the --real tails. mc stays exact-matched,
so `aura mc --real` falls through to usage + exit(2) — Fork A: MC excluded (its
seed varies a synthetic price-walk, undefined over real data).
- Gated integration tests (skip on no local data): sweep --real EURUSD persists 4
portable member dirs over real bars and charts; walkforward --real EURUSD
persists one oos<ns> dir per rolling window; same real sweep twice is
byte-identical (C1). Un-gated: un-vetted symbol, window-without-real, and
mc --real each refuse with exit 2.
- Remove the now-redundant `#[allow(dead_code)]` from the Task-1 provider: every
const, both enums, and every method are live once the wiring lands.
Verified end-to-end over real EURUSD data: sweep --real -> 4 members; walkforward
--real over 2024 -> 9 rolling OOS windows; all refusals exit 2. Full workspace
test + clippy -D warnings green.
