Fix macOS overlay launch: faster capture, no Space thrash, Raycast-safe

Drop osascript fullscreen exit and slow focus hacks; capture immediately
and show a high-level CanJoinAllSpaces overlay. Avoid mutually exclusive
NSWindowCollectionBehavior flags that aborted under Raycast, harden
activation for non-UI script hosts, and document installing to PATH.

+### Install to PATH (needed for Raycast)
+
+Raycast scripts usually resolve `moomer` via `~/.local/bin`. After every rebuild:
+
+```bash
+$ cargo build --release

+### Raycast Script Command
+
+Import or paste `scripts/moomer-raycast.sh` as a Raycast Script Command:
+
+- **Mode:** Silent  
+- Runs `~/.local/bin/moomer` detached (`nohup`) so Raycast doesn’t kill the overlay  
+- Logs: `/tmp/moomer.log` and `/tmp/moomer.raycast.out`
+
+If Raycast “does nothing”, check those logs — a stale `~/.local/bin/moomer` was a common cause (it crashed on launch).
