v4.5.1

respin of v4.5.0 for macos 26: same source tree (the wine1115 branch of dappermint/winecx at the same pinned commit), rebuilt on the hosted macos 26 lane where the sdk matches the 26.0 floor.

v4.5.0 was built on a macos 27 host, and its ntdll.so weak-imported pipe2, a macos 27 api: below 27 the first server-pipe call jumps through a null stub and a prefix cannot boot (#3). this build's ntdll carries no pipe2 reference, every binary is minos 26.0, and the new undefined-symbol audit ran authoritative and clean: every undefined symbol in all 693 bundled mach-o files checked against the sdk's stubs plus the bundle's own exports, weak imports included.

use this build on macos 26 and up. v4.5.0 works only on macos 27 and its notes now say so.

everything else from the v4.5.0 notes applies unchanged: steam's ui end to end, d3d12 through d3dmetal at feature level 12_2, dxvk d3d11, msync (WINEMSYNC=0 workaround if a black steam appears on a heavily loaded machine), the full media stack, wine-mono 11.2.0, faudio 26.08.

install: unpack Libraries.tar.gz over whisky's Libraries directory, run wineboot -u once per existing bottle. gptk payloads deploy the same way as before, symlinks not copies.
