🌌 Z4 — dimensions: MY PATCHES → DIMENSIONS (framing) + dimension zero

A dimension is everything (the whole scene: routes, tweaks, grooves, tempo);
a vibe is a feeling you can hand a friend. Same /api/presets storage — this is
a framing rename, existing saves appear unchanged.

- ⚙ panel: 'MY PATCHES' → 'DIMENSIONS', copy reworked; input placeholder
  'name this dimension…'.
- the load dropdown always leads with '✦ dimension zero — the empty field';
  loading it calls enterZero() (the place you build from nothing).
- grimoire 'Saving your instrument' rewritten (canon = truth): the dimension /
  vibe distinction, the GSV1 share code + #vibe= link, 'build a vibe, save a
  vibe, share a vibe'.

Verified live (z0test): panel shows DIMENSIONS + ✨ VIBES, MY PATCHES gone,
dropdown leads with dimension zero. Console clean, syntax clean.

+<p><b>Vibes — a feeling, shareable.</b> A dimension is a hard scene save of the whole instrument; a <b>vibe</b> is smaller and lighter — a little bundle of specific source→voice cables, the exact combo that made a moment sing. Right-click a spinning orb in zero (or any node in the full field) → <b>💾 save as vibe</b>, or open <b>✨ vibes</b> (the zero pill, or ⚙). Applying a vibe is <i>additive</i> — it lays its cables on top of whatever you already have and can be toggled straight back off, and it never touches a cable you built by hand. Then <b>⧉ copy</b> the vibe's code (a short <kbd>GSV1…</kbd> string) and paste it to a friend, or share a <kbd>godstrument.pro/#vibe=…</kbd> link — they see <i>“someone shared a vibe”</i> and choose whether to add it. Build a vibe, save a vibe, share a vibe.</p>
