Plugins

Plugin compiler with a blueprint registry (scaffold → validate → deploy) exposed as a runtime service, three model tools, and a blueprint-gallery settings page.

Unifies every DSH extensibility seam behind one declarative DSL: a runtime `fabric` service, `fabric_extend`/`fabric_inspect` tools, and a capability-graph settings page.

Plugin-button aggregator with carrier + on-site-LLM extensibility: gather any plugin's scattered buttons into one entry (SSiD title bar / web floating ball), LLM registers per environment, right-click deregisters — pure data, no plugin source touched.
