Swarm Workspace

Owns the per-subagent git-worktree lifecycle over a two-tier filesystem, so swarm subagents can edit and build in parallel without colliding.

Two-tier filesystem

Path	Role	Rules
`/mnt/agents/output/app`	Shared coordination repo. A plain git repo (no remote). The branch-creation / merge hub.	Do NOT build or edit code here.
`$HOME/app-<branch>`	Local worktree. Fast filesystem where a subagent edits and builds.	Each subagent uses a unique path.
