feat(samples): create publishable headless-search-vite sample (Lit + Vite)

[alexprudhomme]

Summary

A vanilla Vite + Lit @coveo/headless search sample, published to npm as a @coveo/create-ui scaffolding template.

What it does

• Search box with query suggestions and instant results, a standalone header search box, facets (incl. a category facet with breadbox support), sort, a numbered pager, breadcrumbs, and a result list — against the searchuisamples sample org.
• Published via pnpm's publishConfig.directory: the shared prepack builder (scripts/build-sample-publish-dir.mjs) emits ./publish with the runnable app and a package.json that keeps build tooling (vite) but drops test-only devDependencies (incl. the internal @coveo/platform-mock-api) and the e2e script. Source package.json is untouched; ./publish is gitignored.

Tested

• pnpm install --frozen-lockfile passes; the lockfile change is a minimal, additive search-vite importer (+ publishDirectory), no transitive drift.
• Builder output verified: publish/ ships the app only (no e2e/), dependencies = @coveo/headless + lit, devDependencies = vite, scripts dev/build/preview.
• oxlint / oxfmt clean; deterministic Playwright smoke test with @coveo/platform-mock-api + MSW.

Rebased onto main (single commit); uses the shared publish builder introduced with the commerce samples.

Pull request overview

Adds a new vanilla JavaScript + Vite sample under samples/headless/search-vite to demonstrate building a Headless-powered search UI (DOM-driven) with basic controllers and a Playwright smoke test.

Changes:

• Introduces a new Vite-based Headless search sample (HTML/CSS/JS) with facets, sorting, pagination, and query summary.
• Adds Playwright E2E scaffolding (MSW-backed mock API) for a basic “page loads and shows results” smoke test.
• Wires the new sample into the workspace lockfile.
