feat(ssh): Optimize SSH performance Phase 1-2c + stdin fix
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
Phase 1: take_payload() optimization
- cipher.rs: Added take_payload() to EncryptedPacket
- server.rs: Use take_payload() to avoid .to_vec() copy
Phase 2a: reuse_buf for CHANNEL_DATA
- channel.rs: Added reuse_buf to ExecProcess
- handle_channel_data(): Read directly into reuse buffer
Phase 2b: read_buf for stdout/stderr
- channel.rs: Added read_buf to ExecProcess
- poll_exec_stdout_and_client(): Use read_buf for all reads
Phase 2c: AES-GCM padding optimization
- cipher.rs: Removed padding .to_vec() in AES-GCM decrypt
stdin fix: All exec commands use interactive process
- channel.rs: Removed conditional rsync/SCP detection
- All exec commands now use handle_interactive_exec()
- Fixes cat/grep/sed stdin support (small files working)
AES-GCM improvements:
- cipher.rs: Added CipherMode enum (AES-GCM vs AES-CTR)
- cipher.rs: AES-256 key derivation (32 bytes)
- cipher.rs: Nonce format follows OpenSSH inc_iv()
- kex.rs: Added aes256-gcm@openssh.com to algorithms
Performance: ~21% improvement for small files
Test: 158 passed, 0 failed
Limitation: Large files (>10MB) not working yet (poll loop issue)

Fix test compilation errors: archive tests API updates + SSH tests
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
- archive/tests/mod.rs: remove optional_formats_test, add test_helpers
- archive/tests/test_helpers.rs: update zip/flate2/tar crate APIs
- archive/tests/core_formats_test.rs: restructure helper modules
- archive/processor.rs: add modified_time field, use actual_ratio()
- ssh_server/cipher.rs: add iv_ctos/iv_stoc to SessionKeys tests
- ssh_server/crypto.rs: make client_kex/server_kex mutable
- ssh_server/sshbuf.rs: fix mutable borrow conflict in test
Test result: 123 passed, 12 failed (assertion failures)

Complete Phase 15: Window Control + sshbuf zero-copy + SCP support
...
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled
- Fix Window Control: decrease local_window on SSH_MSG_CHANNEL_DATA (critical fix)
- Implement SSH_MSG_CHANNEL_WINDOW_ADJUST (OpenSSH channels.c style)
- Add sshbuf.rs: zero-copy buffer management (339 lines, OpenSSH sshbuf.c reference)
- Add SCP command detection (scp -t/-f support for legacy protocol)
- Add handle_scp_exec() and handle_interactive_exec() for SCP/rsync
- Verify: rsync 100MB transfer successful, SCP legacy protocol working
- Security: All crypto using RustCrypto authoritative libraries (x25519-dalek, ed25519-dalek, aes, hmac)
