This PR updates dmux so a pane workspace can manage selected nested repositories alongside the root repo and keep them aligned across create, reopen, resume, bootstrap, and cleanup flows.
Scattered source updates, isolated context, and manual follow-up across multiple feeds.
Introduces pane-level linked child-repo selection and state persistence, making nested repositories first-class lifecycle participants (create, reopen, resume, bootstrap, cleanup) instead of being detached from the pane’s root repository management.
Developers managing related repos in one dmux pane can keep workspace state consistent after restarts, so nested repos are less likely to drift out of sync or require manual repair during resume/cleanup. The PR stores linked-repo metadata in the worktree state and threads it through lifecycle transitions, reducing operational overhead for multi-repo setups and lowering the chance of orphaned or misaligned child repos. Continue monitoring whether existing single-repo workflows remain unaffected, whether migration of older worktree metadata is reliable, and how failures are surfaced when a linked repo is missing or partially configured during bootstrap.
