rdmpw3275m-changelog-20260829-0046-git-config-normalization

Normalized safe global Git defaults on rdmpw3275m while preserving its authenticated Intel Homebrew GitHub CLI workflow and all repository state.

Scope and exact changes

• Updated /Users/richh/.gitconfig additively with the twelve-key shared fleet Git contract: richhdoty noreply identity, user.useConfigOnly, main, fast-forward-only pulls, fetch pruning, simple/upstream pushes, rebase autostash, zdiff3, rerere, and worktree remote guessing.
• Changed /Users/richh/.gitconfig mode from 644 to 600.
• Created /Users/richh/.gitconfig.bak-git-sync-20260829-004609.
• Preserved the existing /usr/local/bin/gh credential-helper entries and authenticated account state; no credential, Keychain, auth/session, repository, .git, branch, commit, remote, or source data moved.
• Homebrew gh 2.98.0 was already present; no installation occurred.

Restore with cp -p /Users/richh/.gitconfig.bak-git-sync-20260829-004609 /Users/richh/.gitconfig, then inspect with git config --global --list --show-origin.

Outstanding owner actions

• None for GitHub CLI authentication on this host.
• Continue using explicit task branches and clean commit/push handoffs to the canonical rdmsm4x integration lane.
