pikuri-code 0.0.5

pikuri-code adds the shell-and-dev-loop layer on top of pikuri-workspace's filesystem tools: a +Pikuri::Code::Bash+ that runs commands via the +Pikuri::Subprocess+ chokepoint with +Confirmer+ gating (optionally wrapped in a +Pikuri::Code::Bash::Sandbox::Bubblewrap+ filesystem sandbox), plus the demo +bin/pikuri-code+ binary that wires file + shell + web tools into an interactive coding agent rooted at the current working directory. The +Pikuri.prompt+ search path picks up this gem's +prompts/coding-system-prompt.txt+ automatically on require.
