/publish-pcf-companion

On-demand deployment of the dispatcher PCF for a third-party .ppmplugin control to a Power Platform environment. The dispatcher PCF is the Studio-side control that dispatches the composite key <name>/<receiver> over the wrap shell's SendMessagePlugin bridge to the control's native module. Runs pac pcf push against the user's active pac auth profile. Decoupled from /generate-pcf-companion — the engineer scaffolds locally, customizes / iterates, then deploys when ready.

Step 1 — Read shared docs and verify prereqs

1. Read shared/shared-instructions.md, shared/naming-conventions.md.

2. Apply the per-skill minimal prereq policy (shared-instructions.md §1.5). This skill needs Node.js 20+ with npm, pac CLI, .NET SDK, and an active pac auth profile. It does not need pnpm.

   Print the prereq status as a visible block per shared-instructions.md §9.2 before continuing:
