Code quality: Dead code — CLI module and send_state::Done/Confirming never used #11

Severity: Low

Several code paths are effectively dead:

1. cli.rs defines Send/Receive commands with clap, but main.rs ignores them (empty match arms)
2. SendState::Done is defined but never transitioned to
3. SendState::Confirming(DiscoveryPeer) is defined but the TUI goes directly from Discovery to Transferring
4. ReceiveState::Listening(u16) stores a port but the Receive tab has no actual receive flow yet
5. Large blocks of commented-out code in tcp_send.rs (lines 216-245) should be removed

Affected Files

• src/cli.rs (entire file)
• src/ui/mod.rs (line 44: Confirming, line 45: Done)
• src/protocol/tcp_send.rs (lines 216-245)

Suggested Fix

• Either implement the CLI flow or remove the module
• Replace unused enum variants with TODO comments or remove them
• Clean up dead code blocks
