feat(registry): add 15 caption style catalog components

Add 15 caption overlay components to the registry, covering a wide
range of animation techniques:

Standalone origins (6):
- caption-pill-karaoke: pill container + karaoke word highlight
- caption-neon-accent: multi-color neon glow with wiggle drift
- caption-weight-shift: font-weight transition between lines
- caption-emoji-pop: emoji + stroked text + horizontal squeeze
- caption-editorial-emphasis: dual-font (Inter + Playfair) emphasis
- caption-parallax-layers: 3D text layering with vertical stretch

Gallery picks (9):
- caption-glitch-rgb: RGB chromatic aberration + CRT scanlines
- caption-typewriter: green terminal char-by-char with cursor
- caption-matrix-decode: scramble-reveal character animation
- caption-particle-burst: keyword particle explosions
- caption-texture-lava: flowing lava texture mask
- caption-clip-wipe: clip-path left-to-right wipe reveal
- caption-kinetic-slam: full-screen single-word slam
- caption-gradient-fill: gradient-clipped text + elastic bounce
- caption-neon-glow: cyan/magenta neon glow accents

Each component includes the reusable HTML, a demo composition,
and registry-item.json. All use a generic HyperFrames transcript.
