v1.0.0 — BREAKING: short alias renamed 'ar' → 'arb'

v1.0.0

First stable release. No more 0.x churn.

⚠️ BREAKING: short alias renamed from ar to arb

The old ar short alias was being shadowed by /usr/bin/ar (the BSD/GNU
archive tool) on shells where npm's global bin comes after /usr/bin in
PATH — common in cloud shells, cron, and shells launched without nvm
initialized. Users running ar --help would see the archive tool's
usage instead of agent-rollback's.

The new short alias is arb (agent-rollback, 3 chars, no collision).

Migration

• agent-rollback has always worked and still does — no change there.
• If you were using ar, switch to arb.
• If ar still appears in your shell after this release, the system
  archive tool is now correctly visible again.

# old
ar list
ar checkpoint "before refactor"

# new
arb list
arb checkpoint "before refactor"

# full name (unchanged)
agent-rollback list

Changes

• bin/ar.js → bin/arb.js (rename, same wrapper)
• package.json#bin: ar mapping removed, arb mapping added
• scripts/install.sh: verifies arb and detects the system-ar shadow
  with a one-line note
• README.md: new "Why is the short alias arb and not ar?" FAQ
  entry, all command examples updated
