* feat(#766): distribute gsd-core as a native Claude Code plugin
Add an additive .claude-plugin/plugin.json manifest plus hooks/hooks.json so gsd-core can be installed as a first-class Claude Code plugin (marketplace or zero-friction @skills-dir), with /gsd-core: namespaced commands and lifecycle management — alongside the unchanged npm/file-copy installer.
- .claude-plugin/plugin.json: validated with 'claude plugin validate --strict'
- hooks/hooks.json: mirrors the installer's always-on Claude hook wiring via ${CLAUDE_PLUGIN_ROOT}
- package.json: ship .claude-plugin in the npm tarball
- tests/issue-766-plugin-manifest.test.cjs: manifest + always-on-hook-contract drift guards
- docs: install-on-your-runtime.md + FEATURES.md
Closes#766

* docs(#766): add ADR-766 + glossary entry for Claude Code Plugin Manifest Module
Record the plugin manifest as the Seam projecting gsd-core's artifact surfaces onto the Claude Code plugin contract (sibling of the Runtime Artifact Layout Module, ADR-3660), with the defined kind->field mapping and the always-on hook projection rule.

GSD uses npm installation (npx get-shit-done-cc) only.
The plugin.json also referenced non-existent auto.md.
