style(setup): lift text weight — prose becomes regular, outcomes bold

Dimmed explanatory prose blocks were hard to read against dark terminals. Shift the weight ladder up a notch:

- dimWrap() no longer dims. Multi-line prose (the step-intro copy, etc.) renders at the terminal's regular weight.
- Spinner outcome labels (done/failed/skipped) are now bold via runUnderSpinner, so each step's headline reads stronger than the body copy around it.
- Un-dim two command-hint blocks in auto.ts (docker-group setfacl + service restart; the socket-error remediation commands) — those are commands the user may need to type.

Dim is still used where it helps — (Ns) spinner timings, URLs, short inline parentheticals — and for the preview/debug blocks dim is explicitly reserved for: dumpTranscriptOnFailure tail and claude-assist streams.
