Replace rkyv/bincode caching with redb indices

Browse source 
Remove three-tier loading (rkyv snapshot, bincode cache, capnp replay)
in favor of direct capnp log replay + redb for indexed access.

- Remove all rkyv derives from types (Node, Relation, enums, etc.)
- Remove Snapshot struct, RKYV_MAGIC, CACHE_MAGIC constants
- Remove load_snapshot_mmap(), save(), save_snapshot()
- Remove MmapView, AnyView from view.rs (keep StoreView trait)
- Simplify Store::load() to just replay capnp logs
- Add db.rs with redb schema: nodes, uuid_to_key, visits, transcript_progress
- Simplify cmd_fsck to just check capnp integrity + graph health

capnp logs remain source of truth; redb indices will be rebuilt on demand.
