feat(tui-spawn-dx): CLI-symmetric agent/team primitives + canonical-UUID invariant

CHANGELOG.md

 ## Unreleased
 
+### Testing
+
+- Added end-to-end integration coverage for the `tui-spawn-dx` wish
+  (`src/__tests__/tui-spawn-dx.integration.test.ts`) and a shell reproducer
+  (`scripts/tests/repro-canonical-uuid.sh`) that locks the three
+  perfect-spawn-hierarchy invariants: canonical UUID stable across
+  dead/alive cycles, canonical never clobbered by parallel creation, and
+  parallels off the auto-resume path.
+
 ### Breaking
 
 - Removed `genie omni bridge`, `genie omni start`, `genie omni stop`, and

scripts/tests/repro-canonical-uuid.sh

+# repro-canonical-uuid.sh — end-to-end reproducer for the tui-spawn-dx wish.
+#
+# Proves the canonical-UUID-per-agent invariant holds against a LIVE genie
+# install (pgserve + compiled CLI). Three "spawns" of the same canonical
+# produce byte-identical `claude_session_id` in the `agents` row.
+#
+# Sequence (mirrors handleWorkerSpawn exactly):
+#   1. findDeadResumable(team, name)      — returns a dead row if one exists
+#   2. resolveSpawnIdentity(name, team)   — only if step 1 returned null
+#   3. registry.register(...)             — UPSERT into agents
+# Between steps, we flip the row's pane_id to 'inline' to simulate the pane
+# dying. findDeadResumable treats 'inline' as dead (isPaneAlive early-exit).
+#
+# Authority: tui-spawn-dx wish, Group 8. Locks the invariant PR #1134
+# (perfect-spawn-hierarchy merge 69215743) established.
+#
+# Usage:
+#   ./scripts/tests/repro-canonical-uuid.sh
+#
+# Exit codes:
+#   0 — all invariants hold
+#   1 — invariant violated (failure message printed above the exit)
+#
+# Isolation: runs against an ephemeral test schema in the live pgserve
+# instance, so it never touches the production `public` schema. The schema
+# is dropped on exit via `trap`.
