v0.13.0

Stash-Free Merge Path

Removed git stash from the merge workflow. Sequential merges no longer silently lose work.

• team_merge now runs git merge --squash + git reset HEAD directly — no stash/pop cycle
• Sequential merges work cleanly: merge A lands unstaged, merge B lands on top, nothing lost
• Conflict messages include full manual resolution steps (git merge --squash + git reset HEAD)

Explicit Tool Messaging

All tool output now tells the lead exactly what happened and what to do next.

• team_shutdown reports commit count: "alice committed 3 changes. Ready to merge." vs "alice has uncommitted changes only"
• team_merge output: "Merged X's changes into your working directory (unstaged). Review with: git diff"
• team_tasks_complete fires a TUI toast with progress: "socializer: 3/7 tasks complete"

Also in this release

• Spawn restriction softened from "CRITICAL: one call per response" to "one at a time, avoids worktree contention"
• Removed stale git stash list references from cleanup overlap warnings
