fix: remove marketing text from runtime prompt, fix #1656 and #1657 (#1672)

* chore: ignore .worktrees directory

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(install): remove marketing taglines from runtime selection prompt

Closes #1654

The runtime selection menu had promotional copy appended to some
entries ("open source, the #1 AI coding platform on OpenRouter",
"open source, free models"). Replaced with just the name and path.

* fix(tests): use process.execPath so tests pass in shells without node on PATH

Three test patterns called bare `node` via shell, which fails in Claude Code
sessions where `node` is not on PATH:

- helpers.cjs string branch: execSync(`node ...`) → execFileSync(process.execPath)
  with a shell-style tokenizer that handles quoted args and inner-quote stripping
- hooks-opt-in.test.cjs: spawnSync('bash', ...) for hooks that call `node`
  internally → spawnHook() wrapper that injects process.execPath dir into PATH
- concurrency-safety.test.cjs: exec(`node ...`) for concurrent patch test
  → exec(`"${process.execPath}" ...`)

* fix: resolve #1656 and #1657 — bash hooks missing from dist, SDK install prompt

#1656: Community bash hooks (gsd-session-state.sh, gsd-validate-commit.sh,
gsd-phase-boundary.sh) were never included in HOOKS_TO_COPY in build-hooks.js,
so hooks/dist/ never contained them and the installer could not copy them to
user machines. Fixed by adding the three .sh files to the copy array with
chmod +x preservation and skipping JS syntax validation for shell scripts.

#1657: promptSdk() called installSdk() which ran `npm install -g @gsd-build/sdk`
— a package that does not exist on npm, causing visible errors during interactive
installs. Removed promptSdk(), installSdk(), --sdk flag, and all call sites.

Regression tests in tests/bugs-1656-1657.test.cjs guard both fixes.

* fix: sort runtime list alphabetically after Claude Code

- Claude Code stays pinned at position 1
- Remaining 10 runtimes sorted A-Z: Antigravity(2), Augment(3), Codex(4),
  Copilot(5), Cursor(6), Gemini(7), Kilo(8), OpenCode(9), Trae(10), Windsurf(11)
- Updated runtimeMap, allRuntimes, and prompt display in promptRuntime()
- Updated multi-runtime-select, kilo-install, copilot-install tests to match

Also fix #1656 regression test: run build-hooks.js in before() hook so
hooks/dist/ is populated on CI (directory is gitignored; build runs via
prepublishOnly before publish, not during npm ci).
