* feat(#1928): remove sunset gemini cli runtime, redirect to antigravity
Google sunset Gemini CLI on 2026-06-18; Antigravity CLI is its official successor (already a first-class GSD runtime). Remove the gemini runtime from the enum (16->15), aliases, labels, config-home fragment, install path, converters (convertClaudeToGemini{Markdown,Toml,Agent}, convertSlashCommandsToGeminiMentions), capability descriptor, gemini-extension.json, RULESET.GEMINI.*, and the interactive menu (renumbered, no gap).
--gemini now prints an explicit deprecation notice citing the 2026-06-18 sunset and redirects to --antigravity (no silent alias, per the issue's Hyrum's-Law rejection). Antigravity is preserved throughout: its GEMINI.md contextFileName, .gemini/antigravity config home, the shared convertGeminiToolName/claudeToGeminiTools tool vocabulary, and the 'gemini' hookEvents dialect it declares. GEMINI.md retargeted as Antigravity's context file.

* chore(#1928): drop Gemini CLI from issue templates (review nit)
Removes the sunset Gemini CLI runtime from the two GitHub issue-template
runtime lists that the removal PR missed, per @davesienkowski's review nit:
- feature_request.yml: 'Applicable runtimes' checkbox (a user could otherwise
request a feature for a runtime GSD no longer supports)
- bug_report.yml: 'Runtime' dropdown + the stale ~/.gemini/settings.json
retrieval-help line
Leaves the post-removal templates fully consistent with the Antigravity redirect.

* feat(#1681): ADR-1239 Phase C-2 — gsd-mcp-server bin entry + lifecycle test [slice 3b]
Phase 4 slice 3b (closes#1681). The companion MCP server bin entry so any
MCP-consuming host connects via 'npx gsd-mcp-server' (or its bin on PATH) and
gets GSD command (point 1) + state IO (point 5) with no bespoke plugin.
- gsd-core/bin/gsd-mcp-server.cjs: #!/usr/bin/env node shim requiring
./lib/mcp-server.cjs + runServer({stdin, stdout}); non-zero exit on fatal
error (justified n/no-process-exit disable). Mirrors gsd-tools.cjs.
- package.json: add 'gsd-mcp-server' bin entry.
- tests/gsd-mcp-server-bin.test.cjs: 3 process-lifecycle tests — initialize +
tools/list round-trip + clean exit, malformed-line -> parse error + server
keeps running, empty stdin -> clean exit. Synchronous spawnSync (bounded;
server exits on stdin EOF, no orphan).
Phase 4 trust-gate (#1806) + loader wiring (#1808) + server module (#1809) +
this bin/lifecycle slice = all of #1681's deliverables. Concrete host binding ->
Phase 5 (#1682). npm-integrity + eslint + security + inventory all clean.
* docs(#1681)+chore(changeset): how-to for the companion MCP server + Added fragment
docs/how-to/connect-gsd-mcp-server.md — Diataxis how-to guide for connecting
any MCP-capable host to gsd-mcp-server: goal-oriented flow (add config → restart
→ verify), real-world per-host conditionals, troubleshooting, and a trimmed
reference table. Explanation/reference linked out (ADR-1239, capability-trust-
model) per Diataxis boundary rules rather than mixed in.
.changeset/humble-seals-rest.md — type: Added (first user-reachable surface of
the epic: a new bin command). The how-to doc satisfies the docs-required gate.
* fix(#1681): move gsd-mcp-server shim to top-level bin/ (out of the runtime-copied tree)
The shim at gsd-core/bin/gsd-mcp-server.cjs was inside the tree the installer
copies into every runtime config dir, so it leaked into all 16 runtimes and
broke golden-install-parity. The MCP server is a PACKAGE bin the host spawns
(npx gsd-mcp-server), not a per-runtime artifact — so it belongs at top-level
bin/ alongside install.js (which is also never copied into a runtime config).
- gsd-core/bin/gsd-mcp-server.cjs -> bin/gsd-mcp-server.js (require path now
../gsd-core/bin/lib/mcp-server.cjs).
- package.json: bin entry -> bin/gsd-mcp-server.js.
- tests/gsd-mcp-server-bin.test.cjs: SHIM path updated.
- eslint.config.mjs: add bin/gsd-mcp-server.js to the bin/install.js block
(drops the n/no-process-exit disable — the n plugin isn't loaded for that
block, so the disable referenced an undefined rule).
golden-install-parity 16/16 restored; lifecycle + unit tests green; eslint 0;
lint:ci all ok.
