test(computer_use): isolate backend env in check_fn test

- Validate direction before key dispatch (unknown values return False)
- Log exceptions instead of silently swallowing them
- Add 150ms delay before overlay restart to avoid DWM race
- Route switch_desktop through _maybe_follow_capture for consistency
- Add JSON Schema if/then to require direction for switch_desktop

-# one tool call per turn multiplies the number of round-trips — and therefore

-# searches, or safe lookups. Batching independent calls into a single
-# assistant response collapses N turns into one, cutting both latency and the
-# resent-context cost that compounds over a long conversation.
-#
-# The hermes-agent runtime already executes a batch of tool calls
-# concurrently when they are independent (read-only tools always; path-scoped
-# file ops when their targets don't overlap — see
-# run_agent._execute_tool_calls / tool_dispatch_helpers). The missing piece
-# was telling the *model* to emit those calls together in the first place.
-# Until now the only batching steer in the prompt lived in

-# got nothing. This block makes the steer universal; the now-redundant
-# Google-only bullet has been dropped so no model receives it twice.

-"""Profile-scoped credential resolution for multi-profile gateway multiplexing.
-
-The multiplexing gateway serves many profiles from one process. Each profile
-has its own ``.env`` with its own provider keys and platform tokens, so we
-**cannot** union them into the process-global ``os.environ`` (that would leak
-profile A's keys to profile B's turns, and to every subprocess spawned with
-``env=dict(os.environ)``).
-
-This module provides a fail-closed, context-local secret scope:
-
-- ``set_secret_scope(mapping)`` installs the active profile's secrets for the
-  current task (a contextvar, so it propagates into the agent's worker thread
-  via ``copy_context()`` exactly like the HERMES_HOME override).
-- ``get_secret(name)`` reads from that scope. When multiplexing is **active**
-  and no scope is set, it RAISES rather than silently falling back to
-  ``os.environ`` — an un-migrated or newly-added call site fails loud at that
-  exact line instead of leaking another profile's value. When multiplexing is
-  **off** (the default), it transparently reads ``os.environ`` so the
-  single-profile gateway and every non-gateway caller behave exactly as before.
-
-Design rationale lives in ``docs/design/multiplexing-gateway.md`` (Workstream A).
