RUSTDOC ICE FIX AND SOLVER UPGRADES SHIP OVERNIGHT

Rustdoc crashed on deprecated notes in re-export chains. That's fixed [ref:15]. Two major rollups just landed with eager param_env normalization and core::io changes that reshape standard library architecture.

The first critical fix lands in rustdoc [1], which was throwing internal compiler errors when deprecated notes appeared on inlined re-export chains. The fix resolves those links from the owning re-export instead, with regression tests in place [2]. On the solver front, two rollups shipped back-to-back. The first enables eager param_env normalization in the new solver [3], a foundational change for type inference. The second rollup [4] adds the `-Zforce-intrinsic-fallback` flag for intrinsic handling, moves `std::io::Seek` into `core::io` to decouple standard library dependencies, and introduces `WriteThroughCursor` to the cursor API. Miri caught upstream changes and pulled them in [5], while the locals handling for Priroda debug-info is now merged [6], improving visibility into projected debug-info places in the locals command. Five crate index updates crossed the wire overnight [7][8][9][10][11], all routine maintenance.
