v0.3.1 — Quickstart hardening & inotify fallback

What's new

Quickstart improvements:

• Auto-registers OpenClaw agents (vault-curator, vault-janitor, vault-distiller, worker) when OpenClaw backend is selected
• Checks Temporal package + server availability with clear messaging ("Alfred's workflows won't work without it")

Curator inotify fallback:

• Periodic inbox rescan every 60s as fallback when inotify doesn't fire (containers, overlayfs, NFS, older kernels)
• Configurable via curator.watcher.rescan_interval in config.yaml

Docs:

• Improved Temporal ImportError messaging in CLI
• Reordered install extras in Installation.md for clarity
