fix(desktop): pass-2 review corrections (round 3) — captured respawn, behavioral tests, residue

Browse Source 
Global-config respawn: replace live-scope wrappers with one transition epoch.
restart_under_captured_epoch acquires managed_agent_runtime_transition +
managed_agents_store_lock, validates captured generation, stops, builds a
captured spawn context (records/personas/global config/owner hex/scope_id
from captured_scope), spawns/registers, saves — no live wrapper past the stop.
persist_last_error takes captured_scope, validates generation under its own
acquired store lock, never called while that lock is held, fails closed on
poison. Two tauri::test::mock_app() tests: fresh-scope no-runtime → Skipped
(proves generation guard passes + path proceeds), stale-scope → Skipped at
generation step (switch-between-stop-and-spawn test, calls production fn).

Behavioral tests on production paths: tauri = { version = "2", features = ["test"] }
added to dev-dependencies. compensate_drain_for extracted with injectable
start_fn; tests call it directly (compensate_drain_for is the production core).
capture_agent_snapshot_import_entry and capture_team_snapshot_import_entry
extracted as testable entry guards; tests call the real production functions
(no-scope reject, owner-mismatch reject, matching-owner passes + relay verified,
stale-generation rejects validate_scope_generation). registerNestNotifications
extracted from useNestNotifications; test imports and calls the real function,
asserts all three event registrations, workspace-degraded toast payload,
unlisten cleanup per event. fail_if_client_mesh_active and mesh_stop_client
tested via tauri::test::mock_builder() with real AppHandle (no-runtime,
client-runtime, no-runtime stop paths). Generalized fail_if_client_mesh_active
and mesh_stop_client to tauri::Runtime to allow mock_app usage.

Residue: _compensation_gate_removed placeholder deleted from AppState.
identity.rs:346-348 comment corrected (guard passed by value, not dropped).
mesh_llm_scope.rs:59-64 stale re-arm comment replaced with accurate Option A note.
Duplicate generation bump at identity.rs:544 removed (clear_active_scope
calls next_scope_generation internally; no second bump needed).

File-size gate: AgentSnapshotImportEntry + capture_agent_snapshot_import_entry
extracted to import_entry.rs (import.rs: 995 lines); TeamSnapshotImportEntry +
capture_team_snapshot_import_entry extracted to team_snapshot_entry.rs
(team_snapshot.rs: 997 lines). Both within the 1000-line ratchet.

* Surface nest-related backend events as toasts.
* Register all nest-related backend event listeners.
*
* Extracted for testability: accepts `listenFn` and `toastFn` as parameters
* so unit tests can inject mocks without a Tauri runtime. The production hook
* calls this with the real `listen` and `toast`.
*
* Returns a cleanup function that calls every unlisten function.
*
* Covered events:
* - `repos-dir-error`: a configured `repos_dir` failed to validate or its
* symlink could not be applied (invalid path, downgrade refused, external
* target gone). Emitted by `apply_workspace` on both the validate-reject
* and the runtime symlink-failure paths, so a bad `repos_dir` is always
* visibly surfaced rather than silently logged to console.
* symlink could not be applied.
* - `legacy-nest-migrated`: the agent's knowledge was carried over from a
* legacy `~/.sprout` nest. Shown once per machine (deduped via
* localStorage); the backend re-emits each launch while `~/.sprout` exists,
* which also covers the event being emitted before this listener mounts.

* - `workspace-degraded`: a post-commit restore step failed after the workspace
* switch succeeded. The switch is live; the degradation is recoverable by
* restarting the app or re-applying the workspace. Event-sync dispatch failure
* does not emit this event (shutdown-time error, no toast surface exists).
