fix(coding-agent): surface thinking for --print-thoughts when hidden

Threading printThoughts only into runPrintMode is too late when
hideThinkingBlock is set (settings or --hide-thinking): the session is
built with hideThinkingSummary=true, so the provider omits reasoning
summaries and --print-thoughts prints nothing. Override hideThinkingBlock
to false for single-shot print mode before session creation, gated on
print mode; an explicit --hide-thinking still wins.
