Model super<name> override aliases are missing on instances created via new()/create()/finders #3515

Summary

$registerModelSuperAliases() (the super<name> override convention from #3325) only runs from Model.cfc:init(). But the #3213 instance fast path builds model instances without calling init(), so instances returned by new(), create(), findByKey(), findAll(returnAs="objects"), etc. never get the super<name> aliases — only the model() class object does.

Repro

// app/models/SuperOverride.cfc (any model that overrides a mixin)
component extends="Model" {
    public string function columnNames() {
        return "wrapped:" & superColumnNames();
    }
}

m = model("superOverride")            // class object — HAS superColumnNames (goes through init())
StructKeyExists(m, "superColumnNames") // true

m2 = model("superOverride").new()     // instance — MISSING superColumnNames
m2.columnNames()                      // throws Wheels.MethodNotFound: superColumnNames

An app model that overrides save() and delegates via this.supersave() (the documented "Overriding Core Methods" pattern) hits The method supersave was not found on every create()/save()/finder-row.

Root cause

The #3213 fast path in global/objects.cfm:$createObjectFromRoot() (the $initModelObject branch) constructs instances with:

local.instance = CreateObject("component", local.component);
local.rv = local.instance.$initModelObject(...);
if (StructKeyExists(local.instance, "onDIcomplete")) { local.instance.onDIcomplete(); }

CreateObject("component", ...) does not invoke init(), so $registerModelSuperAliases() never fires for these instances. The legacy DI path (getInstance()) and the model() class object both do call init(), which is why the class-object assertion in SuperOverrideSpec passes while instances break.

Why the existing test missed it

tests/specs/controller/SuperOverrideSpec.cfc ("registers super for a model override, unchanged") asserts StructKeyExists(m, "superColumnNames") on g.model("superOverride") — the class object — not on a .new()/.create() instance.

Suggested fix

Register the aliases on the one hook every instance path runs: call $registerModelSuperAliases() at the top of Model.cfc:$initModelObject() (in addition to init()). It is idempotent ($registerModelSuperAliases skips names that already resolve on this), so the legacy/DI path that calls both init() and $initModelObject() is unaffected.

Impact

Silent 500s for any app model that overrides a model mixin and delegates to the framework original via super<name>. Not caught by the current framework suite.
