Keep cache-affecting analysis helpers internal.

HotReloadCompiledCallers is now public, so application code can call FindCallSites or WarmUpCallSitesAsync without BeginRunAsync. FindCallSites reads an entry from the shared cache and then uses it after TryGetOrLoad returns. Without a run hold, a concurrent backfill can evict and dispose that entry while the scanner is using it. The analysis can then fail.

Keep these helpers internal, or require a run created by BeginRunAsync before they can access the cache.

Suggested fix

+internal List<HotReloadCallSiteHit> FindCallSites(string projectRoot, HotReloadCompiledMethodIdentity[] targets)

Review comment at
@Packages/src/Editor/FirstPartyTools/HotReload/CompiledCallers/HotReloadCompiledCallers.cs
at line 15:
Make FindCallSites and WarmUpCallSitesAsync internal in HotReloadCompiledCallers
so application code cannot access the shared cache without a run hold.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
