Bug: CLI subcommands parsed but ignored — TUI always launches regardless #5

Severity: High

In main.rs lines 28-42, when CLI args are provided, the Send and Receive commands are matched but both branches are empty — execution falls through and always launches the TUI. The CLI parser (clap) is set up in cli.rs but never actually used for headless transfers. This means lightspeed send file.txt or lightspeed receive just opens the TUI and does nothing with the arguments.

Affected Files

• src/main.rs (lines 28-42)
• src/cli.rs (entire file — unused for actual functionality)

Suggested Fix

Either:

• Implement the CLI send/receive flow (useful for scripting/headless transfers)
• Or remove the clap dependency and CLI module if TUI-only is the intent
• Add a --tui flag that explicitly launches the TUI, making the default CLI path work for automation
