Version 0.6.3 - See changelog for updates.

[jscott3201]

Added

• Interactive shell session state: target command to set/show/clear default target address; status command shows transport, local address, BBMD registration, and discovered device count
• BBMD auto-renewal in interactive shell: register stores registration and spawns background task to renew at 80% TTL; unregister cancels renewal; shown in status output
• Missing shell commands now available interactively: ack-alarm/ack, time-sync/ts, create-object, delete-object, read-range/rr
• Shell discover --bbmd: register as foreign device and discover in one step (BIP shell only)
• Colored terminal output via owo-colors: green for success/values, red for errors, yellow for warnings, cyan for addresses, dimmed for metadata
• Default target auto-prepend: commands like read, write, subscribe use the session default target when no target argument is given
• Discovery progress feedback: "Waiting Ns for responses..." status line during WhoIs

Changed

• Deduplicated format_mac() and device_info() into output.rs (removed from discover.rs and router.rs)
• Removed dead code: is_tty(), print_ok(), print_value() from output module
• BIP shell separated from generic shell for type-safe BBMD command dispatch

Fixed

• Interactive discover --target returning "No devices found" on subsequent calls (removed stale HashSet filter)
• Unused import use bacnet_encoding::npdu::Npdu in bacnet-network/src/layer.rs
