feat: declare adapter plugin capabilities on ServerAdapterModule

Adds supportsInstructionsBundle, instructionsPathKey, and
requiresMaterializedRuntimeSkills flags so the UI renders the
bundle editor for claude_k8s agents. Bumps adapter-utils peer
dep to the canary that includes the capability type fields.
