fix(web): reuse text nodes for dynamic text in multi slots

normalize leaves primitives raw (pure compute; no allocation or DOM
writes in transition forks) and insertExpression materializes them at
commit, adopting the positional text node with a .data write. Previously
every changed text value beside an element sibling allocated a
replacement node and swapped it in, roughly halving update throughput on
dbmon-style workloads. Hydration claiming still adopts server text
nodes; a failed claim keeps the old phantom-render semantics.
