* 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.

**Cross-runtime lifecycle hooks (1.4.0):** Each supported runtime registers lifecycle hook events for per-turn context-headroom tracking and workflow state management. Notable registrations:
- **Claude Code:** `SubagentStop`, `Stop`, `PreCompact` (context-headroom warnings), `FileChanged` (hot-reloads `.planning/config.json` mid-session)
- **Gemini:** `BeforeAgent`, `AfterAgent`, `BeforeModel`
- **Qwen Code:** `SubagentStop`, `Stop`, `PreCompact`
- **Codex:** `SubagentStart`, `Stop`, `PostToolUse` (new in 1.4.0); on Windows the `SessionStart` hook entry gains a `commandWindows` field so the `.cmd` shim is used for native execution

**Runtime-specific enrichments (1.4.0):**
- Codex emits `service_tier: flex` for light-tier agents; GSD skills appear in the Codex `/skills` picker via `SKILL.md` (no `agents/openai.yaml` sidecar is emitted — doing so caused duplicate autocomplete entries, #1326)
- Gemini commands use native `{{args}}` interpolation
**Native packaging:**
- **Claude Code:** GSD Core ships a `.claude-plugin/plugin.json` manifest, enabling installation and lifecycle management via `claude plugin install|enable|disable|update gsd-core`. Commands load under the `/gsd-core:` namespace (e.g. `/gsd-core:plan-phase`), avoiding slash-command collisions with the classic npm installer which uses `/gsd:`. Always-on guard and update hooks are wired automatically via `hooks/hooks.json`. The plugin path is additive — the npm installer (`npx @opengsd/gsd-core`) remains fully supported.
- **Gemini CLI:** Ships `gemini-extension.json`, enabling installation and lifecycle management via `gemini extensions install|update|uninstall|link`.
