Make high-current PCB guidance available as an independent plugin

Add the released design and review workflow for BMS, power switches and distribution boards, including the reusable review template.

Constraint: Reuse the external-source adapter and latest-stable Gitea release flow; installation remains AVAILABLE.
Confidence: high
Scope-risk: narrow
Directive: Update the source repository and release version, then regenerate the plugin with the sync script.
Tested: Marketplace validator; plugin validator; exact generated skill/source equality; unchanged existing entries; source tag and release verification.
Not-tested: Codex install behavior; EDA execution; physical hardware performance.
