PacketWeave 0.1.2

• Add nonblocking, bounded background file ingestion with one outstanding indexed chunk per transfer.
• Enforce global/per-owner session limits without retaining whole asset files.
• Add cumulative remote-receipt waiting with timeout, cancellation and stale receipt rejection.
• Clean partial files off the caller thread after cancellation, disconnect, expiry and shutdown.
• Test 60 MiB content parity, blocked disk backpressure, limits, replay/order, failure and cleanup.
• Keep cancellation effective through final validation and retry partial-file cleanup within session limits.
• Add bounded multi-packet executor batches for latency-sensitive file downloads.
