Add integration tests for libsql-server bottomless replication restore behavior when interrupted by various failure modes. Tests verify sqld can resume and complete an interrupted restore from S3-compatible object storage (minio) without requiring a restart. Test cases: - basic_restore: Sanity check that sqld restores from minio - sqld_interrupted: sqld killed mid-restore, restarted, completes - minio_interrupted: minio stopped mid-restore, restarted, sqld retries - network_partition: sqld disconnected from network mid-restore, reconnected Infrastructure: - Docker-based fixtures with isolated networks per test - Unique container/network names and ports via atomic counters - Port mapping (not host networking) for isolation - Automatic cleanup of Docker resources after each test Files added: - tests/bottomless/mod.rs - tests/bottomless/fixtures.rs - tests/bottomless/basic_restore.rs - tests/bottomless/sqld_interrupted.rs - tests/bottomless/minio_interrupted.rs - tests/bottomless/network_partition.rs - tests/bottomless/README.md Files modified: - tests/tests.rs: Add bottomless module - Cargo.toml: Add reqwest dev-dependency, remove duplicate hex
- Add LIBSQL_BOTTOMLESS_S3_READ_TIMEOUT_SECS (default 5s) - Add LIBSQL_BOTTOMLESS_S3_CONNECT_TIMEOUT_SECS (default 5s) - Add LIBSQL_BOTTOMLESS_S3_OPERATION_ATTEMPT_TIMEOUT_SECS (default 10s) - Configure TimeoutConfig on aws_sdk_s3::Config in bottomless::replicator::Options::client_config() - Update meta_store.rs Options construction to include new timeout fields - Remove #[ignore] from network_partition test - Fix test fixtures: endpoint timing, image caching, mut minio

I'm happy to discuss and/or rework this, but I found that sqld did not recover when object storage was non-responsive.
Adding timeouts to the S3 library fixes this for me, and failures are detected.
