- Add logging.Logf as the canonical printf-style logger type used across feedkit.
- Update scheduler and dispatch to alias their Logger types to logging.Logf.
- Eliminates type-mismatch friction when wiring one log function through the system.
- Add dispatch.CompileRoutes(*config.Config) ([]dispatch.Route, error)
- Compiles config routes into dispatch routes with event.ParseKind normalization.
- If routes: is omitted, defaults to “all sinks receive all kinds”.
- Expand config param helpers for both SourceConfig and SinkConfig
- Add ParamBool/ParamInt/ParamDuration/ParamStringSlice (+ Default variants).
- Supports common YAML-decoded types (bool/int/float/string, []any, etc.)
- Keeps driver code cleaner and reduces repeated type assertions.
- Fix Postgres sink validation error prefix ("postgres sink", not "rabbitmq sink").
