Add web deployment layer and docs for browser-based setup

Pull ttyd/zellij/clide-launcher scripts into deploy/ so the web access
layer lives with the project. Zellij is configured in locked mode with a
bare layout so it only provides session persistence without intercepting
keys or showing UI. Remove Ctrl+G goto-line binding from Clide to avoid
conflict with Zellij's unlock key.
