Install the focused guard test runner from wheels only

[brettheap]

Summary

Follow up on openRepoTools#135's late Sonar annotation: install the focused
guard test runner using --only-binary=:all: so pip cannot execute source
package build scripts. Preserve the pinned pytest version and canonical wrapper.

Runtime guard behavior and vendored command bytes are unchanged.
Implementation: specs/003-binary-only-guard-runner/.

CI reruns the focused guard and hygiene checks and Sonar analysis.
This session is outside a lane under brettheap/new-workstation#47.

Summary by Sourcery

Install the focused guard test runner from wheels only while preserving its pinned version and existing runtime behavior.

Bug Fixes:

• Require the focused guard job to install its pinned pytest runner from binary distributions only, preventing source package build scripts from executing.

CI:

• Document validation of the wheel-only runner installation through the focused guard and hygiene checks.

Chores:

• Add implementation specification and task tracking for the binary-only guard runner change.

Reviewer's Guide

The focused guard workflow now installs pytest 8.3.4 with pip restricted to wheels, preventing source-package build scripts while leaving guard behavior, command bytes, and the canonical verification suite unchanged; accompanying spec artifacts document the correction and validation.
