* 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.

* docs: add design spec for /gsd-ultraplan-phase beta command
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat: add /gsd-ultraplan-phase [BETA] command
Offloads GSD plan phase to Claude Code's ultraplan cloud infrastructure.
Plan drafts remotely while terminal stays free; browser UI for inline
comments and revisions; imports back via existing /gsd-import --from.
Intentionally isolated from /gsd-plan-phase so upstream ultraplan changes
cannot break the core planning pipeline.
Closes#2374

* fix: resolve 5 pre-existing test failures before PR
- ARCHITECTURE.md: update command count 75→80 and workflow count 72→77
(stale doc counts; also incremented by new ultraplan-phase files)
- sketch.md: add TEXT_MODE plain-text fallback for AskUserQuestion (#2012)
- read-guard.test.cjs: clear CLAUDECODE env var alongside CLAUDE_SESSION_ID
so positive-path hook tests pass when run inside a Claude Code session

* fix: address CodeRabbit review — MD040 fence labels and sketch.md TEXT_MODE duplicate
- Add language identifiers to all unlabeled fenced blocks in
ultraplan-phase.md and design spec (resolves MD040)
- Remove duplicate TEXT_MODE explanation from sketch.md mood_intake step
(was identical to the banner step definition)
- Make AskUserQuestion conditional explicit in mood_intake prose
