grabbit a2d49137f9 Add comprehensive test suite: 63 integration tests + 110 Rust unit tests
Integration tests (tests/):
- 9 categories covering config, lifecycle, signals, supervision,
  cache, writeback, network faults, crash recovery, and CLI
- Shell-based harness with mock NAS (network namespace + SFTP),
  fault injection (tc netem), and power loss simulation
- TAP format runner (run-all.sh) with proper SKIP detection

Rust unit tests (warpgate/src/):
- 110 tests across 14 modules, all passing in 0.01s
- Config parsing, defaults validation, RestartTracker logic,
  RC API response parsing, rclone arg generation, service
  config generation, CLI output formatting, warmup path logic
