feat(#69): nest concrete skills under namespace routers at install (#883)

Browse Source 
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.

#### Two-stage hierarchical routing (v1.40, [#2792](https://github.com/open-gsd/gsd-core/issues/2792))
To keep the eager skill-listing token cost low, v1.40 introduces six namespace **meta-skills** (`gsd-workflow`, `gsd-project`, `gsd-quality`, `gsd-context`, `gsd-manage`, `gsd-ideate` — sourced from `commands/gsd/ns-*.md`, but the invocable `name:` is the bare form shown here) layered above the concrete sub-skills. The model sees 6 namespace routers (~120 tokens) instead of a flat 86-skill listing (~2,150 tokens), selects a namespace, then routes to the concrete sub-skill via a routing table embedded in the namespace router's body. Namespace skills are **additive** — every concrete command is still directly invocable.
To keep the eager skill-listing token cost low, v1.40 introduces six namespace **meta-skills** (`gsd-workflow`, `gsd-project`, `gsd-quality`, `gsd-context`, `gsd-manage`, `gsd-ideate` — sourced from `commands/gsd/ns-*.md`, but the invocable `name:` is the bare form shown here) layered above the concrete sub-skills. On runtimes with non-recursive skill loaders (claude global, cline, qwen, hermes, augment, trae, antigravity) the installer now realizes this fully: it emits only the 6 namespace router bundles as top-level skills and nests the ~61 concrete skills under `<router>/skills/<name>/SKILL.md`, so the eager listing is ≈6 entries instead of ≈67. The model selects a namespace router, which instructs it to read the nested concrete skill file via a routing table embedded in the router body. On these runtimes concrete skills are **not** directly invocable by bare name via the Skill tool; they are reachable through the router. Slash commands (`/gsd-*`, via the separate commands surface) are unaffected where the runtime has one. On runtimes with recursive or unconfirmed skill loaders (cursor, codex, copilot, windsurf, codebuddy, opencode, kilo) the layout remains flat — all skills emitted at the top level as before.
The router descriptions use pipe-separated keyword tags (≤ 60 chars) per the Tool Attention research showing keyword-dense tags outperform prose for routing at ~40 % the token cost.
