Public export snapshot from a clean committed source.

Why

macos-13 is the Intel runner class GitHub is retiring. It queue-starved two consecutive release runs, blocking the sign job and therefore preventing any release from publishing at all, even though the other four targets built successfully.

macos-14 cross-compiles to x86_64-apple-darwin natively, so Intel Mac users still get a native binary. Rosetta translates Intel to ARM and not the reverse, so an Intel Mac cannot run the arm64 build; dropping the target would have abandoned those users rather than inconveniencing them. Intel hardware is frozen at macOS 26 Tahoe but supported into 2028.

No change to the artifacts, the seven-asset manifest, or the release contract. Only the machine that builds one archive changes.

Validation

PASS public snapshot / drift guard: source_commit=9c2e7da... files=125
PASS Phase 1 through Slice 3.4 fast gate   (exit 0)

Prior run confirmed the Windows fix works: x86_64-pc-windows-msvc, both Linux targets, and aarch64-apple-darwin all built successfully.

Rebase-merge, not squash.
