Warren e221f86031 Phase 3: Large file test report - Critical issue discovered ...

- Issue: SSH packet size exceeds client maxpack limit (32781 > 32768)
- Impact: Large file transfer fails, file incomplete
- Severity: ⭐⭐⭐⭐⭐ Critical (blocks all SFTP large file transfers)
- Status: SSH server stable (no crash), but transfers incomplete

Test results:
- 5MB upload: 2.0MB (incomplete)
- 5MB download: 0B (failed)
- MD5 check: Failed

Root cause: SSH server violates RFC 4254 Section 5.3
- SSH_MSG_CHANNEL_DATA packet must not exceed client maxpack
- OpenSSH client maxpack: 32768 bytes

Next step: Phase 4 (highest priority)
- Add client_maxpack field to Channel structure
- Fix SSH_FXP_READDIR: chunk file list (max 320 files per packet)
- Fix SSH_FXP_DATA: chunk data (max 32KB per packet)
- Add packet size validation before sending

Estimated work: ~200 lines, ~1 hour
