docs: record Daniel's static-captures ruling on the wavetable direction

R1 (2026-08-03) closes F5 — no frame-indexed wavetables yet — deferring W1 with
"yet" preserved as scope rather than rejection, and confirming W3 out. Near-term
scope narrows to W0 alone. Cascades the consequences: F1's threshold amended
(static does not mean one-cycle, so detection classifies nothing now), F2
simplified, F3 and F7 firmed, F8 narrowed to a binary. F6/band-limiting left
open and explicitly not pre-ruled. PLAN.md item 4 updated to match.

+   that is out of scope. just static captures right now."* It closes fork F5 (the
+   wavetable-position knob does not ship now), confirms the multi-frame wavetable kind out by
+   ruling rather than only by the doc's argument, and **narrows the near-term scope to the
+   doc's W0 — loop-grid recalibration for micro material, which is defect-class work with no
+   new parameter, no format change and no `process()` involvement.** *"Yet"* is recorded as a
+   scope ruling, not a rejection; the doc keeps the deferred case whole and names the single
+   trigger that would revive it. **The ruling does NOT settle band-limiting** — the question
+   that decides it is still outstanding with Daniel, and nothing in the doc pre-rules it. Per
