An unsound analysis in coroutine MIR saved local remapping just shipped, plugging a hole discovered while working on async-drop code.

The fix [1] addresses a critical flaw where the counter variable in array drop glue wasn't correctly identified as a saved local, and indices in ProjectionElem::Index weren't being patched when those locals were saved. This was found during async-drop development and represents real soundness risk. In related compiler work, the borrowck module got a structural cleanup [2] that removes the entire BlameConstraint struct by using vector indices to reference OutlivesConstraint instead, making the code simpler without changing behavior. Bootstrap also received a small but meaningful refactor [3] replacing ShouldRun::crates with crate_or_deps_filtered, addressing a long-standing TODO in the build system. Language-side, track_caller support now works on extern function item declarations [4], filling in a gap where the catch-all attr handler was incorrectly rejecting the attribute. Across crates.io-index, routine crate updates continue [5][6][7].
