Switch agent job image to Fedora with QoL CLI tooling + neutral shell defaults

- Base fedora:41; reinstall toolchain (node 22, gcc/c++, neovim, tmux, git, etc.)
- Add QoL CLI from the user's Panama setup, all in default Fedora repos: zoxide,
  eza, bat, fzf, fd, gh, gum, ripgrep, bash-completion; oh-my-posh via installer;
  pnpm/yarn/bun via npm; keep codex@0.142.0 + opencode@1.17.9 pinned
- Ship neutral system-wide defaults that work even with an empty/mounted HOME:
  /etc/profile.d/spoon.sh (zoxide/eza/fzf/oh-my-posh init + aliases),
  /etc/tmux.conf (login-shell panes), /etc/spoon/omp.json (default prompt theme)
- .dockerignore: re-include docker/agent-job-rootfs into the build context
- Verified: codex runs a real turn on Fedora (exit 0); all tools present
