What and why

The missing-feature error introduced in #1577 ends, when the element has more than three features, with a "did you mean …?" suggestion. missingFeatureMessage passed the whole Candidates list — every feature of the element, sorted by name — to suggest.With, which offers the first Limit entries in the order given. The suggestion therefore named the first three features alphabetically, not the ones nearest to the missing segment, while Frontier.Nearest on the same record already held the right answer:

$ sysml nested.sysml -run-query "Nest::Deep source=Nest::root2"    # root2::y::sub::sub has count, runa, runb, runz
sysml: query Nest::Deep reads feature sub.sub.runs of Nest::root2::y, but the path stops at Nest::root2::y::sub::sub: its features are count, runa, runb, runz — did you mean count, runa or runb?

Now the message ranks the candidates with suggest.Nearest(segment, e.Candidates) first, so the same query says did you mean runa, runb or runz?. The record (Candidates, Frontier) is unchanged; only the sentence moves.

Specification basis

No specification clause: a diagnostic wording fix. docs/internals/design/query-outcomes.md describes Frontier.nearest as "the closest spelling, by edit distance"; the sentence now agrees with the record.

How it was verified

• TestExecuteMissingFeatureSuggestsTheNearestFeatures (new, internal/doc/queryexec/missing_feature_test.go) fails on develop with the message above and passes with the fix.
• go test -count=1 ./internal/doc/queryexec/..., go vet ./internal/doc/queryexec, gofmt -l clean.
• Re-ran the probe above against a binary built from this branch.

Checklist

• make test and make lint pass locally (the touched package; the full suite runs in CI)
• Tests added or updated for the change
• Documentation extended where it already covers the surface (see CONTRIBUTING.md) — no documented example shows the suggestion
• Changelog entry added as changes/unreleased/<slug>.<section>.md, not as an edit to CHANGELOG.md
• baselines regenerated and make docs-counts run if a gate count moved (compliance rows need nothing: the census is counted at docs build) — no count moved
• No internal work-item labels (waves, slices, F4, K5) in the body, docs, or changelog
