Tom Boucher a3aa0ae142 feat(#775): ship a gemini-extension.json extension package (#818)
Add a Gemini CLI extension package so users can install, update, and
remove GSD through Gemini's own extension lifecycle and have it appear in
`gemini extensions list`:

  gemini extensions install https://github.com/open-gsd/gsd-core
  gemini extensions update gsd-core
  gemini extensions uninstall gsd-core
  gemini extensions link /path/to/gsd-core   # dev

This mirrors the additive Claude Code plugin manifest (#766): a thin,
version-stamped manifest enforced by an in-repo drift test. The extension
ships the context-file payload (GEMINI.md), loaded into every Gemini
session; slash-command/agent/hook TOML projection into the extension is a
documented follow-up. The manual `npx gsd-core --gemini` installer (which
provides the /gsd:* commands) is unchanged — purely additive, no breaking
change.

- gemini-extension.json: name=binName, version tracks package.json,
  description, contextFileName=GEMINI.md (minimal; no mcpServers — gsd
  ships no MCP server)
- GEMINI.md: Gemini-session context payload
- package.json: add both artifacts to files[] so they publish
- CONTEXT.md: add "Gemini Extension Package" glossary entry
- docs: USER-GUIDE + install-on-your-runtime how-to
- tests/issue-775-gemini-extension.test.cjs: manifest validity, version
  parity with package.json, contextFileName existence, files[] publication

Closes #775
