refactor(e2e): extract workflow infrastructure into conftest, one test file per workflow

BEFORE: Giant monolith test files with duplicated device stubs, config
factories, and cognitive stack builders. The infrastructure was copy-pasted
into each file.

AFTER: Clean separation:
- conftest.py: E2EDeviceStub, e2e_device, e2e_cognitive_stack,
  e2e_session, e2e_workflow_ctx fixtures
- test_workflow_permission_dialog.py: Permission dialog recovery
- test_workflow_foreign_app.py: Foreign app (Chrome) recovery
- test_workflow_normal_feed.py: Normal post processing
- test_workflow_plugin_integrity.py: Import + interface sanity

Each workflow file is <100 lines. Zero duplication. Every test uses
the shared e2e_workflow_ctx fixture which runs the EXACT code path
from bot_flow.py:942-971.

DELETED: test_full_workflow_hostile_env.py, test_plugin_chain_hostile_env.py
(monolith files replaced by the above)
