Add WebP support and exclude SVG files from image processing

[Claude]

Adds WebP format support to the Gulp image pipeline while explicitly excluding SVG files from processing.

Changes

• gulpfile.config.js: Changed image source glob from **/*.* to **/*.{png,jpg,jpeg,gif,webp} to explicitly include WebP and exclude SVG
• package.json: Added imagemin-webp@^6.0.0 dependency
• gulpfile.js: Refactored imagemin configuration from object syntax to explicit plugins array, adding imageminWebp with 75% quality setting

Behavior

Previously, the wildcard pattern **/*.* accepted all files including SVGs, which were optimized via imagemin-svgo. Now:

• WebP images are processed and optimized alongside existing formats (PNG, JPEG, GIF)
• SVG files in src/img/ are ignored and excluded from the build output
• All processed images continue to generate both original and _minified versions in dist/img/
