Sync Shadcn

Handle $ARGUMENTS. Read the complete sync policy, then the selected mode below. pstack's poteto-mode owns lifecycle and existing authority, the lead writes every change, and a plan takes the plan-page shape; this skill owns upstream range accounting, Plate forks, slice decisions and sync state.

Plate's docs app is a forked product. Upstream owns the Fumadocs/shadcn docs architecture; Plate owns editor content, demos, registry, API MDX, CN docs, MCP, Plate Plus hooks, GA and intentional forks. Keep that ownership explicit.
