* feat(cli): add canonical `crewai create tool` command
Unify tool scaffolding under the create verb and deprecate
`crewai tool create` with a yellow warning while keeping backward
compatibility.
* feat(cli): add canonical `crewai create skill` command
Unify skill scaffolding under the create verb and deprecate
`crewai skill create` with a yellow warning while keeping backward
compatibility.
* feat(cli): add canonical `crewai create template` command
Unify template scaffolding under the create verb and deprecate
`crewai template add` with a yellow warning while keeping backward
compatibility.
* docs: document unified `crewai create` scaffolding commands
Document canonical create forms for tool, skill, and template projects,
note deprecated aliases, and update skills and agents-md guides.
* feat(cli): extend create picker and DMN guidance for all types
Show tool, skill, and template in the interactive create picker and
list every supported type in the CREWAI_DMN usage error.
* fix(cli): allow create tool/skill/template in CREWAI_DMN mode
Only set skip_provider in DMN mode for crew creation, since tool,
skill, and template paths reject that flag as a crew-only option.
* test(cli): patch TemplateCommand at cli lookup site in DMN test
create() resolves TemplateCommand from crewai_cli.cli, not from
remote_template.main directly.
