Stacked on #819. Groups each element's reactive bindings (:props, content interpolation) into one codegen effect entry instead of one per binding, cutting registered effects from #bindings to #dynamic-elements.

What changed:

• src/lib/codegenerator/generator.js: generateElementCode and the prop loop in generateComponentCode buffer statements and flush one combined entry via a new flushElementEffects helper.
• :for safety: buffered statements are split by the existing scope regex, so iteration-only bindings merge into one inner per-item effect while outer-scope bindings stay in the outer loop wrapper (no O(n) regression for mixed bindings).
• Single-statement output is byte-identical to before.

Tests: updated 4 goldens (2->1, 3->1, 2->1, 2->1); multi-element cases unchanged (Poster stays at 4). New codegen test pins inner/outer split-and-merge in loops; new renderComponent tests pin effect counts (3 bindings -> 2 effects) and mixed loop updates. Full suite 1550/1550, eslint clean.
