docs(catalog): add claude-ask-questions to community preset catalog (#2191)

* feat: add claude-ask-questions preset for AskUserQuestion rendering

Delivers the /speckit.clarify and /speckit.checklist AskUserQuestion
integration as a stackable preset under presets/claude-ask-questions/
instead of modifying core templates or ClaudeIntegration.

- presets/claude-ask-questions/preset.yml registers command overrides
  for speckit.clarify and speckit.checklist following the same pattern
  as the bundled lean preset.
- Override commands replace the Markdown-table question-rendering
  blocks with AskUserQuestion instructions. Option | Description maps
  to {label, description} for clarify; Option | Candidate | Why It
  Matters maps to {label: Candidate, description: Why It Matters} for
  checklist. Recommended option is placed first with a
  "Recommended — <reasoning>" prefix; a final "Custom"/"Short" option
  preserves the free-form ≤5-word escape hatch.
- Registered in presets/catalog.json as a bundled preset.

Core templates, ClaudeIntegration, and the existing test suite are
left untouched, so non-Claude agents and users who do not install
this preset see no behavior change.

Closes github/spec-kit#2181

* refactor: move claude-ask-questions preset to external repo

Per maintainer feedback on #2191, presets should be hosted on the
author's own GitHub repository and registered in catalog.community.json
rather than bundled in spec-kit. Removes the bundled preset directory
and its entry from the official catalog, and adds a community catalog
entry pointing at the external repository and release archive.

* docs(catalog): sync claude-ask-questions description with upstream preset

* revert: keep presets/catalog.json updated_at unchanged

No entries in the official catalog changed in this PR, so the timestamp
bump was spurious. Addresses Copilot review feedback on #2191.
