Stabilize local dev daemon homes

Use a checkout-local .dev/paseo-home for root and worktree dev flows so development daemons do not collide with the packaged app home.

Split server, app, and desktop dev entrypoints, seed worktree homes from the source checkout metadata, and keep desktop dev on its own user-data directory and Expo port.
