Rename kernel_api dir to waku_node and tidy node module layout
Why these changes hang together:

- Rename `waku/node/kernel_api/` to `waku/node/waku_node/`: the folder
  holds the node's protocol APIs, so it should carry the node's name
  rather than the legacy "kernel_api" label.

- Collapse the old `kernel_api.nim` aggregator into the top-level
  `waku/waku_node.nim` barrel, and drop `net_config`/`health_monitor`
  from it. Those aren't the node's concern; consumers that used them
  now import them directly (clearer, explicit deps).

- Move the `WakuNode` type from `node_types.nim` into `waku_node.nim`.
  `node_types.nim` only existed to dodge a `WakuNode`/`SubscriptionManager`
  import cycle that Nim actually handles fine, so the type now lives in
  one obvious home and the indirection module is deleted.

- Extract `ShardSubscription` and `EdgeFilterSubState` into their own
  small modules: they are standalone value types with no back-reference
  to the node. `SubscriptionManager` stays with `WakuNode` on purpose
  (it is the node's subscription subsystem; the relationship is real).

Verified: `wakunode2` and `libwaku` build; representative node tests pass.
