v0.3.0

v0.3.0 — 2026-10-11

• Move the installer's default pinned runtime from the v0.1.0 release commit to
  the v0.2.0 release commit (21b3a08), so unflagged bash install.sh installs
  the 0.2.0 CLI. Docs, skill guidance and offline regressions now describe the
  new pin.
• Rewrite the documentation site for the 0.2.0 CLI: a concise 8-step setup
  guide with a sticky progress stepper, an illustrative replay of a cmail setup
  session built from real CLI output, a token-permission mock, a nameserver swap
  diagram and per-step "Done when" checks. Add CLI docs, changelog and privacy
  pages. Checklist progress moves to the cmail:setup-progress:v2 key (older
  14-step progress is not carried over). The site no longer documents the old
  pinned source snapshot; the README keeps that history.
• Setup guide: move "add your domain to Cloudflare" before cmail setup (now
  step 4, setup is step 5) and mark it as needed only when the domain is not on
  Cloudflare yet. The step now points to Cloudflare's own "Add a domain" flow
  and nameserver instructions. Saved checklist progress is keyed by step ID, so
  existing ticks still load (#26).
• Setup guide: show a congratulations card asking for a GitHub star once all 8
  steps are checked. It hides again when a step is unchecked or progress is
  reset, and its state is restored on reload (#27).
• Install with one command, without cloning:
  curl -fsSL https://raw.githubusercontent.com/luongnv89/cmail/main/install.sh | bash.
  The installer no longer fails when piped (it previously stopped with
  BASH_SOURCE[0]: unbound variable), runs nothing if the download is cut
  short, and says whether ~/.local/bin is already on PATH or prints the
  export PATH line to add. It still downloads the pinned v0.2.0 runtime;
  bash install.sh and bash install.sh --local from a checkout keep working.
  The README, setup guide and CLI docs now lead with the one-line command (#25).
