Pull request overview
Fixes the DocFX documentation version picker so /versions/latest/ correctly shows latest as the selected dropdown option by removing dead URL-resolution logic and adjusting how the latest entry is handled.
Changes:
- Removed an unreachable “resolve
latestto a concrete version” block that could never match by URL structure. - Adjusted picker rendering to include the
latestoption when appropriate so/versions/latest/can display a selectedlatestentry.
Same fix as ETL-Xml#187 (0ab73c1) for the identical bug fanned out to this repo. Copilot on #204 flagged that `currentVersion` defaulted to 'latest' on non-versioned pages, so the skip predicate `v.version === 'latest' && currentVersion !== 'latest'` never fired there — surfacing `latest` in the picker outside /versions/latest/. Change the default from 'latest' to `null`. Behavior now matches the PR title exactly: - /versions/latest/ → currentVersion='latest' → latest included, selected - /versions/v0.8.1/ → currentVersion='v0.8.1' → latest skipped - non-versioned pgs → currentVersion=null → latest skipped, none selected Also updated the inline comment to describe starts-null semantics.

Summary
Fan-out of Try-Pattern PR #247. The version-picker JS had a dead URL-match resolution block that tried to match the
latestalias URL (/<repo>/versions/latest/) against concrete version URLs (/<repo>/versions/vX.Y.Z/) — structurally different by construction, so the match NEVER succeeded. The render loop then unconditionally skipped thelatestentry, leaving no option selected on/versions/latest/.Fix: delete the dead resolution block; keep
latestas a first-class option ONLY when the reader is on/versions/latest/. On concrete-version pages the skip still applies — no redundantlatest + vX.Y.Zpair.Same patch, same file. Direct fan-out of Try-Pattern's canonical.
