Fixed mining and timeout settings

- Pending biome reads no longer cancel block breaking
- Custom loot resolves saved biome history after accepted breaks
- Native drops survive failed reads and runtime teardown without duplication
- Tree felling captures the original tool for fallback drops
- Modded block loot resolves one historical biome context
- Timeout settings persist atomically through the actual server configuration paths
- Tests cover deferred loot, teardown and timeout persistence
