EMOJI HANDLING BUG FIXED IN LIVEVIEW, ECTO SUBQUERY ORDER CORRECTED

Phoenix LiveView's HTMLFormatter was mangling multi-codepoint emojis in templates, and Ecto's query builder had subquery ordering issues - both now fixed.

Phoenix LiveView shipped a fix for a subtle but nasty bug where the HTMLFormatter was inserting extra characters when templates contained multi-codepoint emojis like the warning symbol ⚠️ [1]. The problem traced back to changes in #2112 that introduced byte-level arithmetic for preserving content in tags, which worked fine for ASCII text but failed when emojis took up more bytes than codepoints [2]. The fix replaces custom newline handling with binary pattern matching and updates line offset calculations to use binary operations instead of codepoint counting. This is the kind of edge case that slips through code review until someone ships a template with an emoji and watches formatting break in production. In the Ecto world, the query builder had its own ordering issue with subqueries [3] [4], now resolved. Neither of these are show-stoppers, but they're the kind of fixes that prevent silent failures in your templates and queries.
