Review: template-no-passed-in-event-handlers

Compared against the original ember-template-lint rule no-passed-in-event-handlers.

What looks good

• The event handler set matches the original exactly (including mouseMove, mouseEnter, mouseLeave which the original groups under "Mouse events" rather than having a separate section).
• Input and Textarea exclusions are correctly handled for both angle-bracket and curly invocations.
• The ignore option schema is implemented and mirrors the original's config shape.
• Both .gjs and .hbs parsers are tested, with good coverage of the valid/invalid cases from the original test suite.
• originallyFrom metadata is present.

Items worth attention

1. ignore config shape differs from original: The original rule's ignore config expects attribute names without the @ prefix (e.g., { ignore: { Foo: ['click'] } }), but the ESLint rule's schema/docs show values with the @ prefix (e.g., ['@click', '@submit']). The implementation checks ignoredAttrs.includes(attr.name) where attr.name includes @. This means the config format is intentionally different from the original. This is fine as a design choice, but worth calling out explicitly in the docs or a migration note so users porting configs know. The original even validates that ignore values do not start with @.

2. Original also checks the isIgnored for curly MustacheStatement: The original rule's isIgnored is called for both ElementNode and MustacheStatement. In this PR, the GlimmerMustacheStatement handler does not check the ignore config at all. This means users cannot configure ignores for curly-style component invocations ({{foo click=...}}).

3. Missing mouseMove, mouseEnter, mouseLeave in original's event set note: Minor -- the original has focusIn and focusOut listed in both the "Mouse events" and "Form events" sections (duplicated in the Set). Your implementation correctly has them only once in the Set, which is fine.

4. No tests for the ignore option: The original test suite includes test cases for the ignore config (both angle-bracket and curly). The PR tests don't exercise the ignore option at all.

Suggestions

• Add tests exercising the ignore option for both <Component> and {{component}} invocations.
• Add ignore support to the GlimmerMustacheStatement handler to match the original.
• Clarify in the docs that the ignore config uses @-prefixed names (unlike the original).

Overall a solid migration. The core detection logic is faithful to the original.
