Fixes #232

What this does

Replaces the basic swirl shader with a full warp tunnel vortex effect triggered when the player enters a portal.

Visual effects

Speed lines — 28 primary + 14 counter-rotating radial streaks fly past
Zoom pull — the scene rushes into the vortex mouth as progress builds
Swirl twist — spiral rotation tightens toward the center
Chromatic aberration — RGB channel split at peak for sci-fi depth
Portal-colored bloom — vortex center glows in the portal's own color
Tunnel rim glow — bright ring at the vortex edge
White flash — screen blanks at the crossing moment

Mechanics

progress uniform drives a sin(progress * PI) bell curve — zero at start/end, peak at 0.5
Each portal's color and destination URL stored in userData at creation time
Navigation fires at progress >= 0.88 (during the flash) so the transition feels seamless
WARP_DURATION extended from 1.5s → 2.2s for the full dramatic arc

- Replace basic swirl shader with full vortex tunnel effect:
  - Radial speed lines (28 primary + 14 counter-rotating) streaking past
  - Zoom pull: scene rushes into the vortex mouth
  - Swirl twist intensifying with portal depth
  - Chromatic aberration at peak for sci-fi feel
  - Portal-colored bloom from vortex center
  - Tunnel rim glow ring
  - White screen flash at crossing moment
- Add progress uniform (0→1) driving bell-curve intensity via sin(progress*PI)
- Portal color tints the warp based on each portal's own color
- Navigate to portal destination URL at flash peak (progress≥0.88)
- Store destinationUrl and portalColor in portal mesh userData
- Extend WARP_DURATION from 1.5s → 2.2s for full dramatic effect
