claude a32dc38d18 feat(std): meaning lines for all 27 shipped node schemas
C29 compile/unit seam, task 3 of the self-description plan: every
aura-std NodeSchema literal threads its one-line doc. Four texts were
corrected against the actual eval/finalize semantics rather than taken
from the plan table verbatim: Delay is a lag-N register (not one-step),
GatedRecorder flushes an ungated final row at finalize, Latch is a
level-sensitive set/reset register (captures no input), SeriesReducer
emits its single summary row at finalize (not per cycle).

Gate: cargo build -p aura-std --lib clean; full std test run follows at
the all-crates gate once strategy/backtest/engine thread their sites
(the earlier per-crate test gate was unsatisfiable in isolation --
std's dev-deps pull crates whose sites belong to later tasks).

Brummel d845c509d3 feat(0071): stage1 breakout candidate — Donchian channel signal (#137)
A second Stage-1 R strategy candidate for the edge-research milestone, a structurally
different trend mechanic than the refuted SMA-momentum: a Donchian channel breakout.
Swaps only the signal leg of the stage1-r graph —
close -> Delay(1) -> {RollingMax,RollingMin}(N) -> {Gt,Gt} -> {Latch,Latch} ->
Sub = bias in {-1,0,+1} — keeping the vol-stop R definition unchanged, so it screens
under the identical R yardstick (clean A/B vs momentum).

- aura-std: new RollingMax / RollingMin nodes (sliding-window extremum via a monotonic
  deque, O(1) amortized; mirror the Sma/Delay ring-buffer shape, warm-up skip-emit,
  C7/C8). The +/-1 direction latch composes from two existing Latch nodes + Sub (no new
  latch type).
- aura-cli: stage1_breakout_graph + a manual-grid stage1_breakout_sweep_family
  (fully-bound graph per point, sidestepping parameter-ganging since one channel length
  drives both rolling nodes); --strategy stage1-breakout + --channel grid flag; usage
  strings updated.
- Causality (C2): one Delay(1) on close feeds both rolling nodes, so each channel covers
  close[t-N..t-1] — the current bar is excluded. Pinned by a contrastive e2e test (a
  strictly rising series up-breaks every warmed bar; a window including the current bar
  never could) plus a +/-1-latch-hold test.

All existing goldens byte-identical (stage1-r/sma/momentum untouched); folded-no-trace
== raw-trace metrics; workspace tests + clippy green.
