refactor: remove the dead OnCreated* constructor hooks

[damyanpetev]

Summary

Follow-up to #286 - instead of documenting all the ctros, removing the redundant ones (most).

Every generated component and event-args type carried a constructor whose only job was to call a partial void OnCreatedIgb<Type>() extensibility hook:

public IgbAccordion() : base()
{
    OnCreatedIgbAccordion();

}

partial void OnCreatedIgbAccordion();

Across src/ there were 143 such constructors and 143 hook declarations, of which exactly two were ever implemented (IgbTabs, IgbChat). For the other 141 types the constructor was a verbatim re-declaration of the implicit default constructor and the hook compiled away to nothing — pure noise in every file, and a misleading "extension point" that no longer reflects how this repo is maintained.

This PR removes the whole pattern.

What changed

Change	Files
Removed the constructor and the unimplemented OnCreatedIgb* hook declaration	141
Inlined the hook body into the constructor and dropped the indirection (IgbChat, IgbTabs)	4
Updated the coding-convention bullet that advertised OnCreatedIgbButton() as the canonical hook example	.github/copilot-instructions.md

Net effect: 146 files, +7 / -1146, with no behavioural change.

The 141 no-op cases

The removed constructors were all public Igb<X>() : base() with a single OnCreatedIgb<X>(); statement, so deleting them leaves the compiler-generated public parameterless constructor, which chains to the same base(). Nothing else in the repo referenced the hooks — .github/copilot-instructions.md was the only non-source mention.

One explicit empty parameterless constructor was deliberately left in place: BlazorPlainObjectAttribute in src/componentsBase/BlazorPlainObjectAttribute.cs is not a component, and its constructor carries the documented public API surface for the attribute.

IgbChat

The hook lived in src/componentsBase/WebInputs/Chat.cs and existed purely to force the Options setter to run once at construction:

partial void OnCreatedIgbChat()
{
    // Ensure that Options setter is called to apply the default options and disable input attachments.
    this.Options = new IgbChatOptions();
}

That assignment moved into the constructor in src/components/Blazor/Chat.cs.

IgbTabs

OnCreatedIgbTabs() wrapped a single call to EnsureChangeHandled(), which is what keeps child IgbTab.Selected in sync when the consumer has not subscribed to Change. The call moved directly into the constructor in src/components/Blazor/Tabs.cs, ahead of the existing collection-adapter setup, preserving the original ordering. EnsureChangeHandled() stays in src/componentsBase/WebInputs/Tabs.cs — it is a real method on the partial class, not a hook.

Verification

• dotnet build IgniteUI.Blazor.Lite.slnx — 0 errors. (6732 warnings, all pre-existing BL0005 noise from the test project setting [Parameter]s directly.)
• dotnet test tests/IgniteUI.Blazor.Tests -f net8.0 — 881 passed, 0 failed, 22 skipped.
• grep -r OnCreated src/ — no matches.

Pull request overview

Removes the repo-wide generated pattern of parameterless constructors that only invoked partial void OnCreatedIgb*() hooks, keeping constructors only where they perform real initialization (e.g., IgbChat, IgbTabs). This reduces noise across the generated Blazor wrapper/component and event-args types while preserving runtime behavior.

Changes:

• Deleted no-op OnCreatedIgb* constructor+hook pairs across many generated component and event-args types.
• Inlined the previously-implemented OnCreatedIgbChat and OnCreatedIgbTabs logic directly into the corresponding constructors.
• Updated .github/copilot-instructions.md to stop advertising OnCreatedIgb* hooks as the canonical extensibility mechanism.
