The image shipped only nvim (EDITOR=nvim), a modal vi-style editor. Add
both a classic and a modern non-modal option so users who aren't
comfortable with vi keybindings have a choice:
- nano (apt): ~2.8 MB installed; deps (libc6, libncursesw6, libtinfo6)
already present via nvim/less/htop/tmux, so no extra packages pulled in.
- micro: ~12 MB single static Go binary from GitHub releases (same pattern
as bat/eza/zoxide). Desktop-style keys (Ctrl+S/Ctrl+Q), mouse, syntax
highlighting. ARG MICRO_VERSION pins; defaults to latest.
Combined ~15 MB (well within the smoke size threshold's ~250 MB headroom,
so no threshold bump). EDITOR stays nvim; both editors are opt-in
(export EDITOR=micro | nano). Uses the canonical micro-editor/micro URL
because the old zyedidia/micro org rename makes /releases/latest redirect
to another /latest, defeating the tag-parsing latest-resolution idiom
(independently verified: old org 302s to micro-editor/micro; both arch
tarballs HTTP 200; latest resolves to v2.0.15).
Base-image change, so it lands on the next base-<hash> rebuild. Updates
README (what's-inside tree + EDITOR note), CHANGELOG (Unreleased/Added),
and smoke-test.sh (nano + micro presence checks). Ported from pi-devbox
3a59e15.
