Rails core shipped fixes for HTML-aware ERB compiler failures and has_many :through association scoping problems that were breaking strict template validation.

The templating fixes [1] address long-standing issues in bundled error templates that fail under Herb's strict HTML5 validation. A stray closing tag in the routing error template dating back to 2013, malformed nesting in action mailbox templates, and SendGrid envelope handling all now pass validation [2]. On the ORM side, association unscope now qualifies values with table names [3], letting has_many :through associations properly respect default scopes on join models without collision. The tailwindcss-rails CI pipeline got fixed to play nice with Dependabot [4] after zizmor validation comments blocked automated updates [5]. Rails website picked up Mike Dalessio as a committer [6] and improved changelog entries by expanding linked PR references [7].
