Closes #90.

install.sh

• A short banner, then clear stages: Resolving version → Downloading → checksum → install. These use the same ⏺ / ⎿ tree as the CLI.
• Green ✓ for steps that worked, dim text for secondary details, a yellow ! for the shadowing-install warning, and a red ✗ error: for errors.
• A separate "next steps" block at the end. It shows the PATH hint (when one is needed), then dcd login and dcd --help.
• Colours are on only when the stream is a terminal. stdout and stderr are checked separately. Colours are off when NO_COLOR is set or TERM is dumb, and then the text is the same with no escape codes.
• It stays POSIX sh (dash -n is clean) and is still wrapped in main(). The curl --progress-bar download is unchanged.

Example output (colour removed):

  dcd · DeviceCloud installer

Progress spinner (src/utils/progress.ts)

• Cyan braille frames (⠋⠙⠹…) instead of clack's magenta ◒◐◓◑. Terminals without Unicode get ASCII frames.
• No │ guide bar. The CLI is a ⏺/⎿ tree, not a clack session.
• The spinner's last line now uses the CLI's own ✓ / ✗, not clack's ◇. The new ux.action.fail() marks a failure. The upload, Moropo and results-polling call sites now use it, and no longer put their own ✓ / ✗ in the message.
• Title and status are joined with a dim · instead of —.
• The CI fallback still prints one plain line per distinct status. The only change there is the ✓ / ✗ on the final line.

Testing

• pnpm lint, pnpm typecheck and pnpm test:unit pass. The new test/unit/progress.test.ts covers the non-interactive path.
• I ran install.sh for real under dash with output piped, under a pseudo-terminal with colour, and with NO_COLOR on a failing download.
• I ran the spinner in a pseudo-terminal to check the frames and the final lines.
