* refactor(#1734): extract install engine from bin/install.js (ADR-1239 Phase B deep move)
Relocate the runtime-artifact install cluster out of the 12,490-line
bin/install.js into a dedicated src/install-engine.cts -> install-engine.cjs:
installRuntimeArtifacts, uninstallRuntimeArtifacts, installOpencodeFamilySkills,
and their cluster helpers (_copyStaged, snapshot/restore, legacy migration,
GSD-entry pruning, preserve/restoreUserArtifacts, OpenCode-family converters,
USER_OWNED_ARTIFACTS).
- bin/install.js imports the engine and re-exports the moved symbols for
back-compat; getCommitAttribution STAYS in install.js (impure config I/O +
argv explicitConfigDir global) and is injected via a resolveAttribution param.
- 17 test files migrated to import the moved symbols from the engine.
- Bookkeeping: eslint built-artifact ignore, .gitignore, INVENTORY manifest+row,
CONTEXT.md Install Engine Module glossary seam.
Behaviour-preserving: install output is byte-identical for all 16 runtimes
(golden-parity harness #1730) — the only delta is the new install-engine.cjs
file shipping in the installed gsd-core/bin/lib/ tree.
Closes#1734

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.

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.
