fix(#947): restore gsd- prefix on Hermes skills for canonical dispatch (#955)

* test(#947): add regression tests and update stale Hermes assertions

- Add bug-947-hermes-gsd-prefix.test.cjs: 12 TDD tests covering fresh
  install canonical layout, bare-stem migration, manifest key format,
  and non-Hermes runtime isolation
- Update hermes-skills-migration.test.cjs: bare-stem → gsd-prefixed
  path and name assertions (#947 canonical layout)
- Update install-nested-layout.test.cjs: Hermes NEST matrix prefix ''
  → 'gsd-'
- Update install-regressions.test.cjs: Defect #1 now seeds bare-stem
  dirs (help/, quick/) and asserts gsd-help/ canonical output; use
  real GSD stems so readGsdCommandNames() migration finds them
- Update install-runtime-artifacts.test.cjs: Hermes nested layout and
  legacy migration assertions align with gsd- prefix
- Update install.test.cjs: Hermes install test uses gsd- prefixed paths
- Update runtime-artifact-layout.test.cjs: prefix '' → 'gsd-'

* fix(#947): restore gsd- prefix on Hermes skills for canonical dispatch

Hermes skills were installing under bare-stem paths
(skills/gsd/<stem>/SKILL.md, name: <stem>) due to prefix: '' set in
ADR-3660 / #3664. This broke /gsd-<stem> dispatch and forced users to
invoke skills without the gsd- namespace prefix.

- src/runtime-artifact-layout.cts: change Hermes skillsKind prefix
  from '' to 'gsd-'; skills now land at skills/gsd/gsd-<stem>/SKILL.md
  with name: gsd-<stem>
- bin/install.js _runLegacyInstallMigrations: invert the #3664
  migration — remove stale bare-stem dirs (using readGsdCommandNames()
  to distinguish GSD-owned stems from user content), keep gsd-* dirs
  which are now canonical
- bin/install.js _runLegacyUninstallCleanup: also remove bare-stem
  dirs on uninstall for clean teardown
- bin/install.js uninstallRuntimeArtifacts: post-cleanup removes
  DESCRIPTION.md and empty skills/gsd/ category dir on Hermes
- bin/install.js: remove skillListPrefix Hermes exception (now uses
  shared 'gsd-' path)
- docs/adr/3660-runtime-artifact-layout-module.md: document #947
  reversal of the bare-stem sub-decision

* chore: add changeset for #947 fix (#955)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(#947): remove ALL pre-migration bare-stem Hermes skills on reinstall (adversarial review)

Replace readGsdCommandNames()-based bare-stem cleanup (which missed skills
not in the commands source tree, e.g. dev-preferences) with
_removeHermesBareStemDirs(), called AFTER the install loop when the exact
set of installed gsd-<stem>/ dirs is authoritative. For every gsd-<stem>/
written this run, the corresponding bare skills/gsd/<stem>/ is removed.
User-owned bare dirs with no gsd-<stem> counterpart are preserved.

Add two adversarial-review regression tests that FAIL on old code:
- bare skills/gsd/dev-preferences/ removed when gsd-dev-preferences/ installed
- user-owned bare dir with no gsd-<stem> counterpart is preserved (no over-deletion)

- Each `ArtifactKind` is `{ kind: 'commands'|'agents'|'skills', destSubpath, prefix, stage }`. `stage` is a function `(resolvedProfile) → stagedDir` that closes over the per-runtime converter where one is needed (e.g. `convertClaudeCommandToClaudeSkill` for the `skills` kind on Claude global).
- The `kinds` array is empty for runtimes with no GSD surface (a hypothetical future runtime with no integration). The `skills` kind is **absent** for runtimes that don't materialize skill directories (Cline; Gemini today). The `commands` kind is **absent** for runtimes that consume only the skills/agents layout (Claude global, Codex, etc.).
- Per-runtime quirks live in the layout's record fields, not in caller branches:
- **Hermes**: `{ kind: 'skills', destSubpath: 'skills/gsd', prefix: '' }` — preserves the nested namespace from #2841.
- **Hermes**: `{ kind: 'skills', destSubpath: 'skills/gsd', prefix: 'gsd-' }` — preserves the nested namespace from #2841. **Note (#947):** The original decision used `prefix: ''` (bare stem) on the incorrect premise that the `skills/gsd/` category directory namespaced the leaf identifier in Hermes's loader. Research showed category dirs are purely organisational; dispatch is by the skill `name:` field. The `gsd-` prefix was restored by #947 to match every other runtime.
- **Cline**: `kinds: []` — Cline resolves to zero kinds in Phase 1 (no `commands` kind).
- **Gemini**: `kinds: [ { kind: 'commands', destSubpath: 'commands/gsd', prefix: 'gsd-' } ]` — no agents, no skills.
- `applySurface` migrates from `(runtimeConfigDir, commandsDir, agentsDir, manifest, clusterMap)` to `(runtimeConfigDir, layout, manifest, clusterMap)`. Body collapses to `for (const kind of layout.kinds) _syncGsdDir(kind.stage(resolved), path.join(layout.configDir, kind.destSubpath), kind.kind)`.
