split into workspace: poc-memory and poc-daemon subcrates

Browse source 
poc-daemon (notification routing, idle timer, IRC, Telegram) was already
fully self-contained with no imports from the poc-memory library. Now it's
a proper separate crate with its own Cargo.toml and capnp schema.

poc-memory retains the store, graph, search, neuro, knowledge, and the
jobkit-based memory maintenance daemon (daemon.rs).

// Append-only Cap'n Proto storage + derived KV cache
//
// Two log files are source of truth:
// nodes.capnp - ContentNode messages
// relations.capnp - Relation messages
//
// The Store struct is the derived cache: latest version per UUID,
// rebuilt from logs when stale. Three-tier load strategy:
// 1. rkyv mmap snapshot (snapshot.rkyv) — ~4ms deserialize
// 2. bincode cache (state.bin) — ~10ms
// 3. capnp log replay — ~40ms
// Staleness: log file sizes embedded in cache headers.
//
// Module layout:
// types.rs — Node, Relation, enums, capnp macros, path helpers
// parse.rs — markdown → MemoryUnit parsing
// view.rs — zero-copy read-only access (StoreView, MmapView)
// persist.rs — load, save, replay, append, snapshot (all disk IO)
// ops.rs — mutations (upsert, delete, decay, cap_degree, etc.)
// mod.rs — re-exports, key resolution, ingestion, rendering
