Subject: [PATCH] perf(edge): enable gzip compression and configure client
 request buffer limits

- Configured gzip compression (level 5, min_length 256 bytes) across text, JSON, and XML MIME types to reduce edge egress bandwidth and latency.
- Set explicit client body (128k) and header buffer (1k default, 4x8k large) thresholds to prevent memory fragmentation and slowloris vector expansion.
- Added automated unit test coverage in tests/test_project.py.
