fix: stop dimming setup card bodies

Clack's `p.note` defaults to `format: e => styleText("dim", e)`, which
fades note bodies regardless of the project's stated readability stance
(see comment on `dimWrap` in setup/lib/theme.ts: "prose renders at the
terminal's regular weight"). The dim styling makes body copy hard to
read on dark terminals and visibly washes out brand-colored segments
embedded in cards (e.g. the chip + bold heading rows).

Add a `note()` helper in setup/lib/theme.ts that wraps `p.note` with a
pass-through formatter, and route every setup-flow `p.note` call site
through it: setup/auto.ts, every setup/channels/*.ts adapter, and the
two setup/lib/claude-* helpers.

Pre-styled segments (brandBold, brandChip, formatPairingCard,
formatCodeCard) now render at full strength instead of being faded
alongside surrounding prose.
