search: make the navigation form work from every page (AUD-151)
The nav form carried hx-get="/search" hx-target="#search-results", but #search-results exists only on /search. On every other page htmx found no target and silently discarded the response: a search box that looks like it works and does nothing. - SearchForm is now a plain GET with no htmx attributes (navigation and the landing page), so it navigates to /search?q=… from any page and with JavaScript disabled. - SearchFormLive keeps the in-place swap on the search page, where the target does exist. For HX-Request the server now returns the block's *contents* (SearchResultsBody), so the fragment no longer nests a second element with id="search-results" inside the live region. - Empty query shows a prompt instead of an empty list. A zero-match query says "Nothing found" and offers the six areas plus the evidence index. - The result count is role="status" inside the existing aria-live container, so a screen reader reads "4 results for …" rather than a run of titles. Tests (internal/server, internal/site): - the nav form carries no htmx attribute on nine pages, and no built page carries an hx-target whose element is missing (walks all of dist/); - search submitted from /, /edge/ and /platform/ lands on a page with results with no HX-Request header, i.e. the JavaScript-disabled path; - empty query, zero match and the announced count; - a content change followed by a build is visible in dist/search.db. That is the deploy path: deploy/deploy.sh runs `make dist` before it stages a release, and search.Build removes and rewrites the index every build. DoD: search from home, /edge and /platform lands on results; works with JavaScript disabled; zero-match query shows a message; content change followed by a deploy is reflected in search; no htmx request targets a missing element.
