Two bugs: upsert_provenance didn't update node.timestamp, so history
showed the original creation date for every version. And native memory
tools (poc-agent dispatch) didn't set POC_PROVENANCE, so all agent
writes showed provenance "manual" instead of "agent:organize" etc.
Fix: set node.timestamp = now_epoch() in upsert_provenance. Thread
provenance through memory::dispatch as Option<&str>, set it via
.env("POC_PROVENANCE") on each subprocess Command. api.rs passes
"agent:{name}" for daemon agent calls.

The POC_PROVENANCE env var lookup was duplicated in upsert,
delete_node, and rename_node. Extract to a single function.

delete_node and rename_node were cloning the previous node version
for the tombstone/rename entry without updating provenance or
timestamp. This made it impossible to tell who deleted a node or
when — the tombstone just inherited whatever the last write had.
Now both operations derive provenance from POC_PROVENANCE env var
(same as upsert) and set timestamp to now.

Add adjust_edge_strength() to Store — modifies strength on all edges
between two nodes, clamped to [0.05, 0.95].
New commands:
- `not-relevant KEY` — weakens ALL edges to the node by 0.01
(bad routing: search found the wrong thing)
- `not-useful KEY` — weakens node weight, not edges
(bad content: search found the right thing but it's not good)
Enhanced `used KEY` — now also strengthens all edges to the node by
0.01, in addition to the existing node weight boost.
Three-tier design: agents adjust by 0.00001 (automatic), conscious
commands adjust by 0.01 (deliberate), manual override sets directly.
All clamped, never hitting 0 or 1.

The Provenance enum couldn't represent agents defined outside the
source code. Replace it with a Text field in the capnp schema so any
agent can write its own provenance label (e.g. "extractor:write",
"rename:tombstone") without a code change.
Schema: rename old enum fields to provenanceOld, add new Text
provenance fields. Old enum kept for reading legacy records.
Migration: from_capnp_migrate() falls back to old enum when the
new text field is empty.
Also adds `poc-memory tail` command for viewing recent store writes.

All write paths (upsert_node, upsert_provenance, delete_node,
rename_node, ingest_units) now hold StoreLock across the full
refresh→check→write cycle. This prevents the race where two
concurrent processes both see a key as "new" and create separate
UUIDs for it.
Adds append_nodes_unlocked() and append_relations_unlocked() for
callers already holding the lock. Adds refresh_nodes() to replay
log tail under lock before deciding create vs update.
Also adds find_duplicates() for detecting existing duplicates
in the log (replays full log, groups live nodes by key).
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).
