fix: Call resize() before init() to set dimensions first

Simpler solution than lazy initialization: effects need correct
dimensions during init() to register auxiliary textures.

Changed initialization order in MainSequence:
- resize() sets width_/height_ FIRST
- init() can then use correct dimensions

Reverted lazy initialization complexity. One-line fix.

Tests: All 36 tests passing, demo runs without error
