allow per-track model + provider overrides

Track block YAML gains optional `model` and `provider` fields. When set,
the track runner passes them through to `createRun` so this specific
track runs on the chosen model/provider; when unset the global default
flows through (`getTrackBlockModel()` + the resolved provider).

The track skill picks up the new fields automatically via the embedded
`z.toJSONSchema(TrackBlockSchema)` and adds an explicit "Do Not Set"
section: copilot leaves them omitted unless the user named a specific
model or provider for the track. Common bad reasons ("might be faster",
"in case it matters", complex instruction) are called out so the
defaults stay the path of least resistance.

Track modal Details tab shows the values when set, in the same
conditional `<dt>/<dd>` style as the lastRun fields.

+
+The schema includes optional ` + "`" + `model` + "`" + ` and ` + "`" + `provider` + "`" + ` fields. **Omit them.** A user-configurable global default already picks the right model and provider for tracks; setting per-track values bypasses that and is almost always wrong.
+
+The only time these belong on a track:
+
+- The user **explicitly** named a model or provider for *this specific track* in their request ("use Claude Opus for this one", "force this track onto OpenAI"). Quote the user's wording back when confirming.
+
+Things that are **not** reasons to set these:
+
+- "Tracks should be fast" / "I want a small model" — that's a global preference, not a per-track one. Leave it; the global default exists.
+- "This track is complex" — write a clearer instruction; don't reach for a different model.
+- "Just to be safe" / "in case it matters" — this is the antipattern. Leave them out.
+- The user changed their main chat model — that has nothing to do with tracks. Leave them out.
+
+When in doubt: omit both fields. Never volunteer them. Never include them in a starter template you suggest. If you find yourself adding them as a sensible default, stop — you're wrong.
