Remove global Postgres schema registration in favor of explicit schema-aware sink factory wiring, and update weatherfeeder to register the Postgres sink explicitly. Add optional per-source HTTP timeout and response body limit overrides while keeping feedkit defaults. Remove remaining legacy source/config compatibility surfaces, including singular kind support and old source registry/type aliases, and migrate weatherfeeder sources to plural `Kinds()` metadata. Clean up related docs, tests, and sample config to match the new Postgres, HTTP, and NATS configuration model.
- Introduce explicit source interfaces: sources.PollSource and sources.StreamSource, with shared sources.Input (Name() only).
- Remove mandatory Kind() from the base source contract to support sources that emit multiple kinds.
- Add config.SourceMode (poll, stream, or omitted/auto) and SourceConfig.Kinds (plural expected kinds), while keeping legacy SourceConfig.Kind for compatibility.
- Enforce mode semantics in config validation (poll requires every, stream forbids every) and detect mode/driver mismatches in sources.Registry.
- Update docs and tests for the new source model and config behavior.
- 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").
