Jonathan Brouwer b17df9b99a Rollup merge of #149952 - Delta17920:fix/149777-range-destructuring, r=fmease ...

Suggest struct pattern when destructuring Range with .. syntax

implemented a new diagnostic in rustc_resolve to detect invalid range destructuring attempts (e.g., let start..end = range). The fix identifies when resolution fails for identifiers acting as range bounds specifically handling cases where bounds are parsed as expressions and suggests the correct struct pattern syntax (std::ops::Range { start, end }). This replaces confusing "cannot find value" errors with actionable help, verified by a new UI test covering various identifier names.

Fixes rust-lang/rust#149777
