redash-query-runner-framework-ported-wholesale-to-r-same
Redash’s query_runner framework (BaseQueryRunner, BaseSQLQueryRunner, module-level register(), REDASH_ENABLED_QUERY_RUNNERS env var) is being ported wholesale into packages/query-runner in R-Same. The ~70 bundled Redash connectors beyond Snowflake are kept as dormant-activatable via config without rebuild. The ParameterizedQuery layer (Mustache rendering, injection-resistant type-checked params) is also ported. This is the architectural foundation of M3.
