Stencil bundles Rollup 4.34.9, which contains a known deadlock bug
(rollup/rollup#5848) that causes watch mode rebuilds to hang
indefinitely at 'generate lazy + source maps'.

The `@rollup/plugin-commonjs` `load` hook calls `this.load()`
internally. With Rollup's `maxParallelFileOps` defaulting to 20,
the outer load calls saturate the file operation queue, and the
nested `this.load()` calls queue behind them — creating a deadlock.

This is triggered on rebuild because Rollup passes all cached modules
(3000+ in a large project) through the load pipeline simultaneously.

Rollup 4.44.0 fixes this by changing the default `maxParallelFileOps`
to Infinity (rollup/rollup#5986).

fixes: #6602

The public type definition of h() does not include a rest parameter
overload for children, even though the runtime implementation accepts
`...children: ChildType[]`. This causes type errors when passing
multiple children as separate arguments, e.g.:

  h('div', null, 'text', h('span', null), h('img', null))

Add an overload accepting `...children: (VNode | string | number)[]`
to both the `h` namespace and the standalone declarations, matching
the runtime behavior.

Also move a misplaced `h(sel, data, children: VNode)` overload that
was separated from the other overloads by the jsx declarations.

fixes: #6181
