Opening the Browser MCP island shows:

Failed to load island: browser_mcp
Failed to load island WASM 'browser_mcp': Island not found (HTTP 404)

Root cause

browser-mcp is in crates/hero_os_app/src/registry.rs and the placeholder arms exist in island_content.rs, but no browser_mcp WASM is produced anywhere in the workspace (no hero_archipelagos_browser* crate, no island-browser-mcp Cargo feature, no hero_browser_app workspace member).

After the hyphen normaliser in 91aba61, props.island_id arrives as browser_mcp, the static-match arms miss, and DynamicIslandLoader requests /hero_os/ui/islands/browser_mcp/hero_archipelagos_browser_mcp.js which doesn't exist -> 404.

Smallest fix

Drop browser-mcp from registry.rs and remove the dead arms in island_content.rs until a real implementation lands (mirrors the intent of fa684af).
