TEMPORARY TEST SCAFFOLDING: isolate Windows arm64 in create_release.yml

DO NOT MERGE THIS COMMIT. It exists only so this migration's Windows
arm64 path can be exercised on its own, without paying for the full
release matrix. Revert it (a single, self-contained commit) before this
PR merges.

Forces every release job's if: to false except the Windows path: all
macOS jobs (release_macos_single_arch, release_macos_universal,
release_macos_cli, build_macos_tui_binaries, release_macos_tui), all
Linux jobs (build_linux_tui_binaries, release_linux_tui,
release_linux_x86, release_linux_cli_x86, build_linux_arm_binaries,
build_linux_cli_arm_binaries, release_linux_arm), and release_web.

Within Windows, isolates the arm64 leg of build_windows_tui_binaries,
release_windows_tui, and release_windows by commenting out the x64
entry in each job's matrix.include, rather than by adding a matrix
condition to the job's if:. jobs.<job_id>.if only has access to the
github, needs, vars, and inputs contexts (see the context availability
table in GitHub's docs); matrix is not among them, so a job-level if:
referencing matrix.arch silently evaluates to an empty-string
comparison and is always false, which would have skipped both legs
instead of isolating one. Pruning the matrix entry at expansion time
avoids that trap entirely: each of those three jobs runs with a single
arm64 leg and no partial-skip aggregation to reason about.

build_windows_binaries is deliberately left running both legs: its x64
leg alone produces the canonical Windows settings schema artifact that
the arm64 legs of release_windows and release_windows_tui download.

send_slack_notif_if_unsuccessful, gate_tui_release_artifacts, and
generate_changelogs need no change: they already gate on
should_publish == 'true', which is false for a manual workflow_dispatch
test run, so they no-op regardless of the above.
