Borrow exclusivity now covers direct uses of the owner, not just creating another borrow. A write or move of an owner (`c.x = 1`, `del`/move, a method call whose `self` is `&mut` or implicit) conflicts with any live borrow; a read (`c.x`, passing it on) conflicts with a live `&mut` borrow. `_BorrowCheckAccess` resolves the root binding of the access place, applies the NLL dead-borrow rule, and is wired into name loads, attribute loads, assignment targets, own moves (field/argument/assignment), and method receivers (the receiver's `self` kind is read from the parameter registry; implicit `self` is treated conservatively as a write). Reads inside a borrow expression are suppressed so `&mut x` is not reported against its own new borrow. The LSP mirrors the same three checks (write target, owner read, method receiver) with the same messages.
