fix(vegas): stop the heaviest plugin doubling across the cycle seam

Smooth Weighted Round-Robin spaces repeats well within a pass, but it
schedules the heaviest item first and usually last as well. The strip
loops, so those two are neighbours: the marquee showed the same plugin
twice running at exactly the one join a within-cycle check cannot see.
Observed on a live rig at 28 slots -- gaps of 6, 7, 7, 7 and then 1.

Rotating the list does not fix it. Rotation preserves the cyclic order
exactly, so it moves where the seam is drawn rather than the adjacency
itself; the trailing entry has to be swapped with one from the middle.

The first version swapped with the first slot that merely fitted, which
undid the spacing this exists to protect -- it moved a repeat from a gap
of 7 into a gap of 2, more clumped than the seam had ever been. It now
picks the candidate furthest from any other appearance, so the repeat
lands in the widest gap.

Left alone when no candidate exists. A plugin holding most of the slots
has to neighbour itself, and scheduling it is better than refusing to.

+### Live Content in the Ticker
+
+By default, live content **preempts** Vegas mode: while any plugin reports
+live priority, the display controller refuses to run the ticker and shows
+that plugin's full-screen display instead. You get a big readable scoreboard,
+but the marquee stops entirely for the duration of the game.
+
+Set `live_in_ticker` to keep the ticker running and let live content take
+**extra turns inside it** instead:
+
+```json
+"vegas_scroll": {
+  "live_in_ticker": true,
+  "live_weight": 3,
+  "favorite_live_weight": 5
+}
+```
+
+#### Why weights exist
+
+The rotation is otherwise a strict round robin — every plugin appears exactly
+once per cycle. With a dozen plugins enabled, a live score comes round once a
+lap and can be minutes old by the time you see it. A weight of *N* gives a
+plugin *N* slots per cycle.
+
+The slots are placed by **Smooth Weighted Round-Robin**, the same scheduler
+the sports plugins use internally to rotate their own games. The important
+property is that repeats are *spread through the cycle* rather than clumped:
+three appearances in a row followed by a long silence would be worse than not
+boosting at all.
+
+Twelve plugins, with a favorite's baseball game and an ordinary live hockey
+game (`live_weight: 3`, `favorite_live_weight: 5`):
+
+```
+baseball > hockey > weather  > clock  > baseball
+stocks   > news   > flights  > baseball > hockey
+calendar > f1     > music    > baseball > tides
+birds    > hockey > baseball
+```
+
+18 slots for 12 plugins. Baseball appears 5 times, hockey 3, everything else
+once, and no plugin ever appears twice in a row — **including across the seam**
+where the cycle loops back on itself. Smooth Weighted Round-Robin schedules the
+heaviest item first and usually last as well, so the strip would otherwise show
+it twice running at exactly the one join a within-cycle check cannot see. The
+trailing repeat is moved into the widest remaining gap. Where a double is
+unavoidable — a plugin holding most of the slots has to neighbour itself — the
+schedule is left as it is.
+
+#### Where the weight comes from
+
+For each plugin in the rotation, in order:
+
+1. **The plugin's own answer.** If it implements
+   `get_vegas_priority_weight()` and returns a number, that wins. This is the
+   only route for favorite-team awareness — the core can see *that* a game is
+   live, but not *whose*, so a scoreboard has to say so itself.
+2. **The core's default.** When the plugin returns `None` (the base-class
+   default), a plugin where both `has_live_priority()` and `has_live_content()`
+   are true gets `live_weight`.
+3. **Everything else** gets 1.
+
+Because of step 2, **existing plugins need no changes** — any scoreboard with
+`live_priority` enabled already gets extra turns. Step 1 is opt-in, for
+plugins that want to distinguish a favorite's game from any other live game.
+
+Weights are clamped to 1–10. A weight of 1 is no boost; a weight below 1 would
+drop the plugin from the rotation entirely, which is never what is meant.
+
+#### Things worth knowing
+
+- **Weights are per plugin, not per game.** A scoreboard showing four live
+  games still occupies one slot at a time, rotating its own games within that
+  slot using its own `favorite_live_boost`. This controls how often the
+  *plugin* comes round.
+- **The ticker is zero-sum.** Giving baseball 5 slots does not make the cycle
+  faster; it makes the cycle *longer* and everything else proportionally
+  rarer. If you want live scores sooner in wall-clock terms, pair this with a
+  smaller `plugins_per_cycle`.
+- **Frequency is not freshness.** Each appearance redraws from the plugin's
+  current data (`refresh_updated_plugins()` drops cached content when a
+  plugin's data changes), but how current that data is depends on the
+  plugin's own `live_update_interval`. Showing a stale score five times a lap
+  is no better than showing it once.
+- **Everything still appears.** A boost never starves another plugin out of
+  the cycle; low-weight plugins keep their single slot.

+
+How many slots per Vegas cycle this plugin should get. Default returns
+`None`, which defers to the core.
+
+The Vegas ticker is otherwise a strict round robin — every plugin appears
+exactly once per cycle — so with a dozen plugins enabled a live score can be
+minutes stale by the time it comes round. A weight of *N* gives the plugin
+*N* slots per cycle, spread evenly through it rather than clumped.
+
+**You usually do not need this.** When the hook returns `None`, the core
+already gives a plugin `vegas_scroll.live_weight` whenever
+`has_live_priority()` and `has_live_content()` are both true. Live sports get
+extra turns with no code at all.
+
+Implement it only when the plugin knows something the core cannot. The
+motivating case is favorite teams — the core can see *that* a game is live,
+but not *whose*:
+
+```python
+def get_vegas_priority_weight(self):
+    if not (self.has_live_priority() and self.has_live_content()):
+        return None                       # let the core decide

+    if self._favorite_is_live():
+        return vegas.get('favorite_live_weight', 5)
+    return vegas.get('live_weight', 3)
+```
+
+The weight is per *plugin*, not per game: a scoreboard showing four live games
+still occupies one slot at a time and rotates its own games within it. Values
+are clamped to 1–10 by the caller. An exception here is caught and logged, and
+the core then falls back to its own live-content check — so a plugin whose
+weight calculation is broken still gets `live_weight` for a game that really
+is live, rather than being demoted to 1.
+
+Only consulted when the user has set `vegas_scroll.live_in_ticker`. With the
+default (`false`) live content preempts Vegas entirely and there is no ticker
+to be weighted within. See
