ELIXIR TIGHTENS XREF EXCLUSIONS, PARSER DIAGNOSTICS GET SMARTER

Elixir is deprecating the xref exclude syntax and shipping a wave of diagnostic improvements that catch more bugs earlier in the compilation pipeline.

The Elixir team deprecated `xref: [exclude: ...]` configuration [1], signaling a shift in how cross-reference checking will work going forward. This is paired with three targeted fixes that improve error reporting across the language. The parser now correctly specifies its input contract [2], matching what the runtime actually receives as a 4-tuple with indentation data. More importantly, Elixir now collects diagnostics across all rescue clauses [3] instead of stopping at the first one, meaning you'll catch multiple errors in exception handling in a single compile pass. The compiler also infers signatures across application boundaries [4], letting it track types and catch mismatches that previously slipped through. Meanwhile, Phoenix Live View clarified how JS display defaults work [5], fixing subtle behavior in client-side interactions.
