sync: copy slash commands to ~/.claude/commands on every sync

Add Phase 5b — one-way repo -> global copy of .claude/commands/*.md after
the pull, so the CLI always loads the latest skills. Idempotent (only
new/changed files) and soft-failing (never aborts a sync). Fixes the drift
where the global command set lagged the repo (e.g. /syncro was ~3 weeks
stale, and feature-request/forum-post/inject-standards/shape-spec were
missing globally) because the automated script skipped the doc's Phase 3.
