Worktrees

byre worktree fix-flaky-tests

creates a linked git worktree on branch fix-flaky-tests (existing or new) and starts a session in it. The worktree inherits the repo’s config, image, and volumes – the agent is already logged in – but runs in its own container against its own checkout, so sessions run side by side. Worktrees you made yourself with git worktree add inherit the same way: just byre develop in them. You pick once where new worktrees live (byre config --global). Commits land in the shared object store, byre status shows every worktree session in the project, and reset/forget name their blast radius before touching anything shared.
