v0.2.0 — Audit fixes, S3 overhaul, restore reliability Fixed:

• Audit log was silently broken — BlockBreakMixin and BlockPlaceMixin were never registered in mixins.json. /cv audit and Web Live Audit now receive events correctly.
• S3 cloud sync failed on ALL providers — replaced manual HTTP Basic Auth with AWS SDK S3Client.putObject() using proper SIGV4 signing. Works with AWS S3, Cloudflare R2, MinIO, Alibaba OSS.
• Restore path broken on dedicated servers — hardcoded "saves/" replaced with EnvType.SERVER auto-detection.
• deleteSnapshot leaked disk space — .zst chunk files are now removed alongside SQLite rows.
• ChunkRestorer falsely counted failed writes as "restored" — injectChunk return value now checked, failures counted correctly.
• ConcurrentHashMap iteration-during-removal in finalizeAllSnapshots — keys snapshot copied before iteration.
• Cloud sync retries silently skipped error_count — now calls markCloudError() on each failure. Improved:
• Layered retention: per-dimension "keep at least 1" instead of global.
• Consumer loop: poll()+sleep replaced with blocking poll(100ms).
