Replace the line-based REPL with a full-screen Bubble Tea TUI in
interactive mode (non-TTY still falls back to the line editor).
Layout (deveco-code inspired, no emoji):
- Top status bar: HomeAgent brand + connection dot + mode + addr
- Scrollable chat viewport with role-based rendering:
You (purple) user messages
小宅 (orange) agent responses
· reasoning dim gray italic, streaming-merged
[ok]/[fail] tool calls with status + truncated result
[sys] builtin command output
[err] errors
- Rounded-border input box with placeholder
- Bottom status bar: spinner while busy / hints + connection state
Key design points:
- reader generation counter prevents stale errors from the old
reader being mistaken for the new one after reconnect
- handleSubmit always returns waitServer when reader is alive,
so server responses to builtin commands like /status are received
- History stored as *History (was copying sync.Mutex by value)
- Chinese CJK wide-char aware word wrap with hanging indent
- /clear /exit /quit handled in TUI; other /cmds still go through
handleBuiltin with output captured to message area
Verified via tmux PTY: /help, /status, /clear, real chat with LLM
(reasoning -> tool_call -> response chain all render correctly).
The local llmsproxy AUTO chain tries 6+ slots across 3 tiers sequentially.
Each failed tier incurs busyWait (2s) + upstream timeout, so a full chain
exhaustion can exceed 120s. The llmsproxy logs showed 143 'context canceled'
errors for the homeagent key — the client gave up before the chain finished.
180s gives the chain enough room to complete before the client timeout fires.
Also remove stale backup files under /usr/local/bin/.
