teknium1 b121a02416 fix(delegate): composite parents can grant their included toolsets to children
_expand_parent_toolsets built the parent's tool surface from each
toolset's declared `tools` only, so a composite parent's `includes` were
invisible: a child of a `debugging` parent (terminal/process_manage +
includes web/file) asking for `file` or `web` was refused, and `safe` /
`hermes-gateway` parents could grant nothing but their own name. Same
root cause as the `_strip_blocked_tools` fix in the previous commit
(#111700, "Related" section).

Both sides of the subset check now use the resolved static surface
(`resolve_toolset(name, include_registry=False)`), so a child may request
any toolset whose real tools the parent genuinely holds, and still never
gains a tool the parent lacks. Candidates that resolve to nothing are not
expanded into (they cannot be a meaningful subset).
