feat(cli): add native TypeScript terminal UI
Rebuild the terminal client on OpenTUI while keeping the Python gateway as the single agent, session, tool, and memory runtime. Preserve a classic prompt fallback and publish version-matched native sidecars for supported platforms.

# nanobot Terminal UI
|
||||
|
||||
The terminal UI is a TypeScript client for nanobot's existing WebSocket gateway. It owns presentation and input only; the Python gateway remains the single implementation of sessions, the agent loop, tools, memory, and security policy.
|
||||
|
||||
```bash
|
||||
bun install --cwd tui
|
||||
bun run --cwd tui check
|
||||
bun run --cwd tui test
|
||||
bun run --cwd tui build
|
||||
```
|
||||
|
||||
`nanobot agent` launches this client, attaches to an existing local gateway or leases one for the process lifetime, and passes an authenticated local endpoint through environment variables. Use `nanobot agent --classic` to run the legacy Python prompt.
|
||||
|
||||
The renderer uses OpenTUI's split-footer mode: transcript rows are committed to native terminal scrollback while the composer remains fixed at the bottom. This preserves normal terminal selection and scrolling instead of implementing a second scroll model.
