🌊 SchemFlow v0.5.14

Critical fix: per-round world provisioning no longer freezes the server. Also adds headless map capture.

🛠️ Fixed — round provisioning froze the main thread

The on-demand provisionRoundWorld from v0.5.13 had two main-thread stalls (normal /schemflow paste was not affected):

• the schematic was pasted synchronously on the main thread (ignoreAir=false), defeating FastAsyncWorldEdit's async edits;
• the void world was created with a generator that triggered a blocking spawn-point search plus a multi-second "Preparing spawn area" pass.

On a large map this dropped TPS and could trip Paper's watchdog ("server stopped responding").

Now:

• the paste runs off the main thread under FastAsyncWorldEdit (plain WorldEdit falls back to the main thread). The returned future still completes on the main thread, so callers can safely teleport players in whenComplete. Round pastes use ignoreAir=true, since a fresh world is all void;
• the void world generator has a fixed spawn location and skips all vanilla generation phases, so world creation no longer blocks.

✅ Verified

Paper 1.21.11 + FastAsyncWorldEdit 2.15.2 + MinIO, 95k-block map, real S3 round-trip:

✨ Added — headless map capture

• /schemflow savemap <world> <x1 y1 z1> <x2 y2 z2> <group> <name> and WorldProvisioner.saveRegionAsMap(pos1, pos2, group, name) → CompletableFuture<Void>: save a region of any world to S3 with the absolute origin preserved. The world folder is loaded for the capture and unloaded afterwards. Built for batch-converting pre-built map worlds without an in-game selection.

⚠️ Anyone on v0.5.13 should update: that release contains the provisioning freeze fixed here.
