feat(install): add Qwen Code runtime support (#2019) (#2077)

Adds Qwen Code as a supported installation target. Users can now run
`npx get-shit-done-cc --qwen` to install all 68+ GSD commands as skills
to `~/.qwen/skills/gsd-*/SKILL.md`, following the same open standard as
Claude Code 2.1.88+.

Changes:
- `bin/install.js`: --qwen flag, getDirName/getGlobalDir/getConfigDirFromHome
  support, QWEN_CONFIG_DIR env var, install/uninstall pipelines, interactive
  picker option 12 (Trae→13, Windsurf→14, All→15), .qwen path replacements in
  copyCommandsAsClaudeSkills and copyWithPathReplacement, legacy commands/gsd
  cleanup, fix processAttribution hardcoded 'claude' → runtime-aware
- `README.md`: Qwen Code in tagline, runtime list, verification commands,
  skills format NOTE, install/uninstall examples, flag reference, env vars
- `tests/qwen-install.test.cjs`: 13 tests covering directory mapping, env var
  precedence, install/uninstall lifecycle, artifact preservation
- `tests/qwen-skills-migration.test.cjs`: 11 tests covering frontmatter
  conversion, path replacement, stale skill cleanup, SKILL.md format validation
- `tests/multi-runtime-select.test.cjs`: Updated for new option numbering

Closes #2019
