fix(release): auto-update Cargo.lock to prevent crates.io failures

CRITICAL FIX - Prevents recurring release blocker:
- Added pre-commit hook to auto-update Cargo.lock when Cargo.toml changes
- Added pre-flight check to dry-run-release.sh to catch uncommitted Cargo.lock
- Committed current Cargo.lock with version 1.7.4

This has killed multiple release attempts. Never again.
