fix(vegas): refresh scroll buffer on live score updates (#299)

Browse Source 
* fix(vegas): refresh scroll buffer when plugins report live data updates

should_recompose() only checked for cycle completion or staging buffer
content, but plugin updates go to _pending_updates — not the staging
buffer. The scroll display kept showing the old pre-rendered image
until the full cycle ended, even though fresh scores were already
fetched and logged.

Add has_pending_updates() check so hot_swap_content() triggers
immediately when plugins have new data.

Fixes #230

* fix(vegas): scope hot-swap to visible segments; use monotonic clock

1. Replace has_pending_updates() with has_pending_updates_for_visible_segments()
   so hot_swap_content() only fires when a pending update affects a plugin that
   is actually in the active scroll buffer (with images). Avoids unnecessary
   recomposition when non-visible plugins report updates.

2. Switch all display-loop timing (start_time, elapsed, _next_live_priority_check)
   from time.time() to time.monotonic() to prevent clock-stepping issues from
   NTP adjustments on Raspberry Pi.
