In auto-rebuild mode, when the cached container file has been regenerated
since the loaded class was first defined (e.g. user edited a config in a
long-running worker, dev server, or MCP introspector), eval a uniquely-named
copy of the new code into memory and return its name. PHP cannot redeclare
a loaded class, so without this fix long-running processes silently keep
serving the original compiled container even when configs change.

The reload branch is gated by autoRebuild=true, so production code paths
are unchanged: cache hit → reuse loaded class without isExpired check,
cache miss → standard include.

Public methods that expose data ContainerPanel and external introspection tools
(Tracy bridge, MCP inspector etc.) previously had to read via Closure binding on
private properties or by reflecting createService* methods.

Also promotes findAutowired() from @internal to public so callers can answer
"is service X autowired for type Y?" without touching internal $wiring.

ContainerPanel switched over: dropped the bindTo() trick on $tags / $instances /
$wiring and the reflection scan for createService*.
