* fix(xurl): use install kind "node" instead of invalid "npm" [AI]
The xurl skill's second installer declares kind "npm", which is not a
valid install kind. The installer switches on spec.kind with cases for
brew/node/go/uv/download and a default of "unsupported installer", so the
entry is dropped -- `openclaw skills info xurl` only offers the brew
option, leaving no install path on machines without Homebrew.
npm-backed installs use kind "node" (which honors
skills.install.nodeManager, default npm). Only kind is changed;
id/package/bins are left as-is.
Verified against openclaw 2026.6.11 in a container:
before (kind: npm): Install options: → Install xurl (brew)
after (kind: node): Install options: → Install @xdevplatform/xurl (npm)
* fix(github): drop non-functional "apt" install entry [AI]
The github skill's second installer declares kind "apt", which is not a
supported install kind (installer switch handles brew/node/go/uv/download
+ default "unsupported installer"). openclaw silently drops it -- `skills
info github` only ever surfaces the brew option -- so the entry is dead,
misleading metadata rather than a working Linux path.
The remaining brew installer is cross-platform (Homebrew runs on Linux),
so removing the dead entry loses no working path. Improving install paths
for Linux users without Homebrew is tracked separately in #57555
(needs-product-decision).
