## Summary
_Claude Code on behalf of Claus Ibsen_
Upgrade TamboUI from 0.3.0 to 0.4.0 and remove workarounds that are no
longer needed:
- **Delete custom `MirroredSparkline`** (456 lines) — replaced by upstream
`DualSparkline` widget now available in TamboUI 0.4. All 4 usages in
`CircuitBreakerTab` and `EndpointsTab` migrated.
- **Remove reflection hack** in `TuiBackendHelper` — the
`JLineBackend(Terminal)` constructor is now public API, replacing the
reflection probe + fallback pattern.
- **Remove class preloading workaround** — deleted
`TuiHelper.preloadClasses()` and its call sites in `CamelMonitor` and
`CamelCatalogTui`. TamboUI 0.4's built-in shutdown hook and macOS terminal
close fix handle clean shutdown without needing eager class loading.
### What's kept (still needed)
- `Signal.handle("INT")` — still needed to exit the TUI run loop on Ctrl+C
(TamboUI's shutdown hook restores terminal state but doesn't call `quit()`)
- `fixControlChars()` — tab-to-8-spaces expansion is still useful (TamboUI
replaces tabs with single space)
- `buffer.clear(area)` before tab rendering — no specific fix for the buffer
diff bleed-through issue in 0.4
## Test plan
- [ ] Build passes: `mvn install -DskipTests` in `camel-jbang-plugin-tui`
- [ ] Run `camel monitor` and verify sparkline charts render correctly on
Endpoints and Circuit Breaker tabs
- [ ] Verify tab switching does not show styled cell bleed-through
- [ ] Verify Ctrl+C exits cleanly without ClassNotFoundException stack traces
