Ben Ren 1138f0b51a Add expanded codebook with 1344x768 and 864x1184 profiles ...

Extends spectral_codebook_v3 from 2 to 4 resolution profiles:
  - 1024x1024 (existing, 100b+100w refs)
  - 1536x2816 (existing, 88 watermarked refs)
  - 1344x768  (new, 154b+364w refs, top carrier coherence 0.946)
  - 864x1184  (new, 268b+295w refs, top carrier coherence 0.979)

Key findings at new resolutions:
  - 1344x768 carriers sit on the vertical axis (fy=0, fx=3..10)
  - 864x1184 carriers are at mid-frequency diagonals (13,-16), (23,-24)
  - Both show distinct carrier structures vs existing profiles,
    confirming resolution-dependent embedding
