fix: terminal shift-left bug and session sidebar naming/filtering
...
- Guard ResizeObserver in terminal against internal xterm DOM changes
by tracking last width/height and only calling fit() on real resize
- Remove padding from .terminal-container and conflicting .xterm height
override that caused measurement mismatches with xterm-addon-fit
- Filter live session sidebar to active statuses only (running, building,
pending) instead of showing all sessions including stopped ones
- Add display name fallback across sidebar, sessions page, and instance
list to prevent blank names when display_name is empty
Quality gates: tsc (pass), eslint (pass)

feat: responsive web terminal with auto-reconnect, heartbeat, and local echo
...
Implements a resilient, responsive web terminal that survives network blips,
provides instant typing feedback, and restores scrollback on reconnect.
Backend changes:
- Add heartbeat tracking (15s ping interval, 60s idle timeout)
- Add message batching (16ms flush window) for efficient I/O
- Add termios echo detection and set_echo_state control messages
- Add graceful session_ended notification before close
- Add ping/pong protocol support
Frontend changes:
- Rewrite TerminalComponent with status bar, connection indicator,
session-ended overlay, reconnect banner, and ResizeObserver
- Add useTerminalConnection hook with:
- Exponential backoff auto-reconnect (1s → 30s max, 10 attempts)
- Heartbeat/ping-pong with latency tracking
- Local echo for printable ASCII with server deduplication
- Resize debounce (200ms) + throttle (500ms)
- Scrollback serialization via xterm-addon-serialize
- Ctrl+Shift+R manual reconnect shortcut
- Add WebSocket protocol types and encoding utilities
- Add xterm-addon-serialize dependency
Tests:
- 16 backend unit tests (TerminalSession + TerminalManager)
- 13 frontend hook tests (connection lifecycle, reconnect, resize,
scrollback, callbacks)
Quality gates:
- Frontend typecheck: clean
- Frontend lint: clean
- Frontend tests: 48 passed
- Backend unit tests: 101 passed
