feat(claude): add /work and /yolo Linear workflow skills

Replace the old /work command with two new skills backed by Linear:
- /work: proper flow (plan, PR, CI iteration, review loop)
- /yolo: fast flow (implement, push directly, done)

Both share common config via linear-common/COMMON.md and use
per-project .claude/linear.json for org, team, build commands, etc.
