shortcut registry keyed (96 -> 73)

shortcuts.ts is data with no component around it, so it carries catalog keys and
ShortcutsModal resolves them -- same shape as the settings sections.

gen-platform-skill.ts also reads this registry to generate the agent-facing SKILL.md,
which docs:check validates. That doc stays in one language, so the generator resolves
against en-GB directly and throws if a key is missing rather than emitting a dot-path
into a file an agent will quote at somebody. The regenerated skill is byte-identical,
which is the check that keying the registry changed nothing an agent reads.
