Sigil 0.2.7.6

Fixed

data-sigil-effects Attribute Content

• Fixed: data-sigil-effects attribute now contains the actual serialized EffectComposerData JSON instead of just "true"
• The attribute now includes the full effect data: shader code (WGSL/GLSL), uniforms, blend modes, etc.
• Example: data-sigil-effects='{"id":"canvas-id","effects":[{"id":"aurora-effect",...}]}'
• Updated both SigilEffectHydrator and WebGLEffectHydrator to read effect data from the attribute
• Fixed HTML entity decoding (', <, >, &) when reading from attributes
• Removed legacy <script id="$canvasId-effects"> element - no longer needed
