OutputLine gains an optional styled-runs payload — a
Vec<OutputSpan> of { byte_range, OutputStyleClass } over the
line text. render_output_line gains a branch: when the payload
is present it renders the text span-by-span, each run's
semantic class (Neutral / Efficient / Expensive /
AutomaticIndex) resolved to a theme colour at render time;
otherwise the existing whole-line kind styling. The echo path
is untouched.
Theme gains `plan_efficient` — a green deliberately distinct
from `system` so green never reads as two things (ADR-0028 §6);
`warning` is reused for expensive steps.
A general per-span output-styling capability (ADR-0016's OOS-3
realized); the query-plan renderer will be its first consumer.
No user-visible change on its own. 1133 passing, clippy clean.
