gen:plugin-skills regenerates skills/gsd-review/SKILL.md from source; next's
committed copy was stale (missing the review.default_reviewers 'No flags' block
present in source). Surfaced by the full build during this forward-port. Not
gated by CI (test.yml runs only build:lib), so it had drifted silently.
Deterministic regen; the only generated file out of sync.

Phase B-provide of epic #1258. Adds a build-generated skills/ dir +
a skills manifest field so plugin-installed GSD exposes gsd-core:<skill>
the native Claude Code way. Closes the gap where plugin-only installs
lacked the skill surface because bin/install.js never ran.
- scripts/gen-plugin-skills.cjs: build step converting commands/gsd/*.md
to skills/gsd-<stem>/SKILL.md via convertClaudeCommandToClaudeSkill
- .claude-plugin/plugin.json: add "skills": "./skills/"
- package.json: add skills to files, gen:plugin-skills to build chain
- tests/issue-766-plugin-manifest.test.cjs: Section H conformance
(manifest field + dir + frontmatter + count parity) + C2 skills symlink
- docs/adr/766-*.md: dated amendment adding skills surface row
- .changeset/rapid-bears-hum.md: type Added
- skills/: 69 generated gsd-<stem>/SKILL.md files (build-committed)
Closes#1596
