docs(cli,skills): teach check as the canonical verification gate

Scaffolded projects' npm run check now invokes the single check command
instead of chaining lint, validate, and inspect (three Chrome boots
become one). The CLI skill, its correctness reference, the entry skill's
capability map, README/docs catalog rows, the Mintlify CLI page (new
check section, deprecation banner on inspect), template CLAUDE/AGENTS
(byte-identical), root CLAUDE/AGENTS, and every creation-workflow skill
that taught the old sequence all point at check. snapshot keeps its
standalone sections; validate/inspect stay documented as deprecated
aliases with their check equivalents.
