Subject: [PATCH] Wire oleks/mcp-chrome into flake-hub

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.
