fix: detect input elements across browser realms

[wojtowicz-artur]

🎯 Changes

Fixes #132

This was a subtle cross realm issue - instanceof checks break for elements coming from places like same-origin iframes. This PR switches ignoreInputs to normalized tagName checks, while keeping the existing behavior unchanged. It also adds a regression test to make sure this case stays fixed

📝 Walkthrough

Walkthrough

isInputElement no longer relies on current-realm DOM constructors. It identifies input-like elements through tagName and properties, adds cross-realm regression coverage, and records a patch release for @tanstack/hotkeys.

Poem

A rabbit hops through realms anew,
Tag names guide what keys should do.
Inputs, selects, textareas align,
While buttons neatly stay in line.
Tests guard the burrow bright—
Patch notes thump into the night.
