Adds mcp-chrome as a flake input (mirroring the woodpecker-peek pattern) and re-exposes two packages: mcp-chrome-wasm-simd (proven green, ~22 s) and mcp-chrome-extension (KNOWN-BROKEN under nix-daemon; exposed for local builds but kept out of the CI matrix to avoid red pipelines). CI warms attic with mcp-chrome-wasm-simd on x86_64-linux and aarch64-linux only; s390x cross and Darwin are out of scope. Closes oleks/mcp-chrome#5.
