Four bundled plugins wrapped get_hermes_home() in a try/except that fell back
to ~/.hermes on ImportError (a2a/protocol._hermes_home, photon/auth
._auth_json_path, google_chat adapter inline, openviking done in the previous
commit). A bundled plugin cannot lose hermes_constants -- each already imports
gateway.* / agent.* from the same tree -- so the fallback was dead code that
was also wrong on Windows (%LOCALAPPDATA%/hermes) and under a profile override.
telegram's gmail-triage verb path used Path.home()/".hermes" outright, ignoring
profiles. mem0/_oss_providers baked os.path.expanduser("~/.hermes/mem0_qdrant")
into VECTOR_PROVIDERS at import time, so the Qdrant default landed in the
user's ~/.hermes for every profile; the default is now a lazy callable resolved
by vector_default_config(provider_id) at setup time. a2a/security.py only
changes its import (it borrowed protocol._hermes_home).
Behavior change: on Windows and under profiles these paths now follow the
active HERMES_HOME (they were previously anchored to ~/.hermes in the impossible
fallback / at import time); the default-profile POSIX layout is unchanged.
Test: tests/plugins/test_plugin_paths_follow_profile.py asserts each resolver
(a2a conversations, photon auth.json, mem0 qdrant default, openviking log)
lands inside a HERMES_HOME ContextVar override; sabotage red for the mem0
import-time constant and the photon ~/.hermes fallback.
