feat(examples): add hemx html pattern gallery

Add examples/html_examples as a copy-pasteable gallery for the first htmx-style HTML UX patterns using exact htmx URL slugs in the page and README. The slice covers click-to-edit, edit-row, delete-row, inline-validation, click-to-load, and active-search with .heml templates, generated resources, server-owned Rust state, and runtime-free selector targeting.
