Update Jamdesk

Updates customer-facing documentation in external repositories (not CLAUDE.md). Locates docs via .jamdesk-docs-path, asks clarifying questions, writes documentation, and verifies with the jamdesk CLI.

Announce: "I'm using the update-jamdesk skill to update your documentation."

Use when: User-facing changes to APIs, CLI commands, UI, config options, component behavior, or docs.json schema/features.

Skip when: Internal refactors, test-only changes, build/CI config, performance work without behavior change.

Common mistake: Changes to docs.json format or config handling are user-facing. Even if the change was made inside the docs repo itself, ask: "Does this introduce or change a config pattern that customers use?" If yes, document it.
