feat(instantsearch): add Vue and JS phase-2 stubs, bump to 1.1 (4/4)

[vascobettencourt]

What does this skill do?

Mirrors the React library-level reference structure to Vue and vanilla JS. Phase 2 deliberately keeps these as honest stubs: library-level rules + autocomplete only. Pattern-level coverage (search results page, custom widgets, middleware, SSR) for Vue/JS lands in a future phase if/when there's demand. Bumps skill version 1.0 → 1.1.

This is part 4 of 4. Stacks on #24 (which stacks on #23, which stacks on #22). Review #22, #23, and #24 first; this PR's diff now contains only its own changes.

What's in this PR

• 8 new files under references/vue/ — technology-rules.md, anti-patterns.md, styling.md, glossary.md, source-of-truth.md, autocomplete/{features,styling,anti-patterns}.md.
• 8 new files under references/js/ — same structure.
• SKILL.md: fills Vue/JS column cells in the source-of-truth table, the autocomplete row of the patterns table, and the library-level references table. Replaces the "React only" coverage note. Bumps version to 1.1.
• evals/evals.json: adds eval 11 (Vue autocomplete) and eval 12 (JS autocomplete) — both directly testing the recommendation flip Sarah called out: @algolia/autocomplete-js is the recommended path for Vue and JS, not an anti-pattern as it is on React.

Notable: the autocomplete story differs by library

For React, @algolia/autocomplete-js is an anti-pattern (React InstantSearch ships EXPERIMENTAL_Autocomplete). For Vue and vanilla JS, @algolia/autocomplete-js is the recommended path because no equivalent ships in vue-instantsearch / instantsearch.js. The Vue and JS autocomplete docs flip this honestly, and evals 11 and 12 enforce that the agent picks the right side of the flip per library.

Reviewer tip

Most files in the Vue and JS folders are parallel mirrors of each other (with framework-appropriate adjustments — kebab-case Vue components, <script setup> examples, vs. JS factory imports). Reading one Vue file plus its JS counterpart will let you trust the rest.

This stacks on #24 (not parallel to it) with three upstream commits in the branch. The "evals.json has 6 prompts" line is also stale, it's at 10 with #23 and #24 included. Worth correcting so we know what to look at.

Also, no evals for Vue/JS autocomplete. The recommendation flips from React (autocomplete-js is the right path here, an anti-pattern there) which is exactly the kind of behavior worth a quick eval.

@sarahdayan addressed all three:

1. Restacked on feat(instantsearch): add React custom widgets, middleware, SSR (3/4) #24 (was on feat(instantsearch): add Source-of-truth check workflow step (1/4) #22). Diff now shows only this PR's changes.
2. Description fixed — stacking note + eval count (12, not 6).
3. Vue + JS autocomplete evals added in e531a89 — eval 11 (Vue) and eval 12 (JS) test the flip you flagged: @algolia/autocomplete-js is the right path on Vue/JS, not an anti-pattern as on React.
