PR #883 nested Claude skills 3 levels deep under gsd-ns-*/skills/<stem>/SKILL.md.
Claude Code's Skill tool scans only one level under ~/.claude/skills/ — nested
concrete skills were never listed and Skill(skill="gsd-plan-phase") calls failed.
Revert to flat layout: all ~61 concrete skills at ~/.claude/skills/gsd-<name>/SKILL.md.
The 6 other runtimes confirmed as non-recursive scanners (cline, qwen, hermes, augment,
trae, antigravity) retain their nested layout — only Claude changes.
Tradeoff: ~61 top-level skill dirs return to the flat install, but they are discoverable
and invokable. Nested concretes were invisible to the Skill tool entirely.

Three test files copy-pasted the concrete-skill->namespace-router CHILD_ROUTER
map verbatim, and two more duplicated an identical local parseRouterRequires
regex. Introduce tests/helpers/nested-layout.cjs that derives the child->router
map from the authoritative commands/gsd/ns-*.md requires: lists once, reusing
the production parseRequires (now exported from install-profiles) plus a
nestedSkillPath(skillsRoot, prefix, stem) helper. Refactor all five test files
to import from it.
Test-only + a single internal export addition; no production behavior change.
Closes#887

Emit the 6 gsd-ns-* routers as the only top-level skill bundles and nest
the ~61 concrete skills under <router>/skills/<name>/SKILL.md on runtimes
with confirmed non-recursive skill loaders (claude global, cline, qwen,
hermes, augment, trae, antigravity). Router bodies rewrite their routing
tables from Skill-tool dispatch to a Read skills/<name>/SKILL.md pattern.
Recursive/unconfirmed loaders (cursor, codex, copilot, windsurf, codebuddy,
opencode, kilo) keep the flat layout. Completes the v1.40 namespace
architecture (#2792) so the eager skill listing drops to ~6 entries.
