fix(examples): use lower-aware slot html updates

Move canonical examples and docs off direct RenderSlotExt render shortcuts so slot updates use generated render/lowering before HTML replacement, preserving runtime metadata for follow-up interactions.

The public facade and generated view modules expose `render(view)` for trusted hemplate-to-`SafeHtml` page and fragment composition, `static_fragment(include_str!(...))` for prototype/static `.heml` fragments that need generated resource lowering as `SafeHtml`, plus `lower(html)` for callers that need the lowered string; `render_html(view)` and `lower_html(html)` remain explicit compatibility aliases. These return `impl IntoEffect`, `SafeHtml`, or lowered HTML at the boundary. Raw `Effect` constructors, opcodes, and `EffectWriter` remain low-level. [north_star]
