Release v0.1.2 · relatedb/relate

Release notes

Element IDs now name their database — elementId() output gains the namespace segment, so the first node reads 4:relate-neo4j:n0 instead of 4:relate:n0 — in the shell, in JSON, and over Bolt; anything parsing element IDs will want the new shape. Example:
```
relate --json "CREATE (n:Person) RETURN elementId(n)"
```
Shortest paths meet in the middle — a shortestPath whose endpoints are property maps now seeks both ends and searches as a pair instead of balling out from one side, measured two orders of magnitude faster on hub-heavy graphs — and every traversal in the engine saves one read per hop besides. Example:
```
relate -d ./friends "MATCH p = shortestPath((a:Person {name: 'Alice'})-[*..6]-(b:Person {name: 'Bob'})) RETURN p"
```
Cleanly-closed stores skip the reopen index rebuild — when the WAL replays nothing, open no longer rebuilds the indexes, so a tidily shut-down store gets to its first row sooner. Example:
```
relate query --database ./friends
```

relate upgrade no longer prints the rename notice after its status line — just the facts, then the skill refresh.
