Custom SVG block icon

[slaFFik]

Problem

The block currently uses the generic "icon": "randomize" dashicon in src/blocks-randomizer/block.json:8. In the inserter and block list view it blends in with other core blocks and gives no hint of what this plugin does.

Proposal

Ship a branded SVG icon that's recognizable in the inserter, breadcrumbs, and list view.

Replace the string icon in block.json with an inline SVG (or a JS-registered icon in src/blocks-randomizer/index.js if you want different icons for inserter vs. breadcrumb).

"icon": {
  "src": "<svg ...>...</svg>"
}

Existing assets in .wp-org/icon.svg may be a starting point — or design a simpler glyph optimized for the 24×24 inserter size (the WP.org listing icon is usually too detailed at that size).

Acceptance criteria

• Custom SVG replaces the randomize dashicon
• Renders cleanly at 24×24 in the inserter
• Works in both light and dark editor themes (uses currentColor for stroke/fill)
• Matches / harmonizes with .wp-org/icon.svg brand

Files

• src/blocks-randomizer/block.json
• src/blocks-randomizer/index.js (if registering via JS)
• .wp-org/icon.svg (reference)
