Unrolled build for #150026
Rollup merge of #150026 - Delta17920:fix/150002-macro-concat-bug, r=jdonszelmann

Fix macro_metavar_expr_concat behavior with nested repetitions

**The Bug**: The `${concat(...)}` expression was using the wrong loop index when inside nested repetitions (like optional groups), causing it to get "stuck" on the first element and generate duplicate code.

**The Fix**: Updated `metavar_expr_concat` in `transcribe.rs` to correctly search the repetition stack (`tscx.repeats`) for the target variable instead of blindly using the last index.

**Tests**:
    Added `tests/ui/macros/concat-nested-repetition.rs.`

Fixes rust-lang/rust#150002

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
