ci(pointer): scan all docs for premature distribution claims

[rogu3bear]

Summary

• broaden the distribution-boundary guard from README-only scanning to all markdown docs
• keep build and git internals excluded from the scan
• pin the expanded scan coverage in IdentityTests

Verification

• ./scripts/check-distribution-boundary.sh
• swift test --package-path apps/macos --filter IdentityTests/testDistributionBoundaryGuardPreventsPrematureDownloadSurface
• git diff --check

Remaining blockers

• Release authority blockers prevent mass-production readiness #71 remains the authority blocker for notarization, Gatekeeper, stable release metadata, and manual evidence before mass-production readiness
