Bundles a string of multi-repo fixes and refactors that came up while testing the feature end-to-end: - workspace_path stored on multi-repo TaskEnvironment was one level too high, so agentctl booted with the wrong WorkDir on cold start; fixed in resolveTaskEnvWorkspacePath + GetWorkspaceInfoForSession. - Stage/Unstage/Discard/Commit/Revert/Reset/Amend now thread `repo` through agentctl client → WS handler → frontend hook → SessionGit fan-out, so the right git repo is targeted (was running at the task root, which isn't a git repo for multi-repo tasks). - agentctl GitLog is multi-repo aware: when no `repo` is specified and per-repo trackers exist, fans out one log per repo and merges sorted newest-first with RepositoryName stamped on each commit. - Per-repo grouping for files (Changes panel) and commits, with collapsible group headers; commits section defaults to collapsed. Algorithm extracted into one generic groupByRepositoryName helper (was copy-pasted three times). - Task creation dialog rewritten around a unified `fs.repositories[]` list — no more "primary vs extras" split. Chip-style row with one pill per repo + branch, "+" to add, x to remove, GitHub URL toggle inline. Discovered (on-machine) repos appear in any chip's dropdown. Removes ~6 fields and 3 helpers from the dialog state. - Branch listing endpoints collapsed to one: GET /workspaces/:id/branches?repository_id=X | path=Y Frontend collapses to a single useBranches hook with a tagged-union source. Drops two HTTP routes, two service methods, two API client funcs, and one whole hook file. Tests added across the chain: workspace_path resolver, sort-commits- by-date, manager poll-mode propagation, RepoSubpaths, chip grouping + collapse + per-repo isLatest, group-by-repo helper, dialog payload builder + chip wiring + discovered-repo flow.
