refactor(javascript): own runtime reconciliation failures

Return expected source and semantic failures from the runtime input owner as tagged Results. Bind source schema validation to concrete schemas, preserve nested active-capture paths, and let unexpected interpretation and derivation failures reach the adapter boundary.

Remove broad protocol-error wrappers, duplicate active identity validation, and redundant JSON result parsing. Migrate parsed-fact consumers and retain CLI/MCP contracts. Relevant source and public-boundary tests pass; six injected implementation-fault controls fail on the prior revision. Live Electron behavior was not exercised.
