feat(opencode): adopt plugin and runner records - #353

Classify plugin problem records and runner run-metadata/artifacts as
system-origin business receipts tied to session lineage; explicitly
exclude operational state (credentials, caches, queues, updater,
telemetry, ledger storage, retention) so it cannot recurse into
receipts. Contextless CLI/shell launches emit an Unknown Mutation
Receipt without adopting filesystem effects. Reuse the #1077 mutation
registry (new plugin/runner ledger routes, operational out-of-scope
routes, cli-action opaque route; version 3) and the #1078 exposure
matrix for display-safe projection with root-deletion retention.
