Review findings (dev review on PR #44007):
1. HIGH — stale page state on profile switch: pages load data on mount
and didn't consume the profile scope, so a page opened under profile A
kept showing A's state while writes silently targeted the newly
selected B. Fixed structurally: ProfileKeyedRoutes wraps the routed
page tree and keys it by the selected profile, remounting every page
(fresh state + refetch) on switch. ChatPage keeps its own remount
(channel keyed on scopedProfile).
2. HIGH — /api/model/auxiliary read was unscoped while /api/model/set
wrote scoped (Models page could show default's aux pins while editing
worker's). Endpoint now takes profile + _profile_scope, added to
PROFILE_SCOPED_PREFIXES, HTTPException re-raise so ghost profiles 404
instead of 500. Regression test asserts read/write symmetry with
differing worker/default aux config.
3. MEDIUM — tools post-setup spawned unscoped from the profile-aware
drawer. Now spawns 'hermes -p <profile> tools post-setup <key>'
(same mechanism as hub installs); drawer threads its profile prop.
Most hooks install machine-level artifacts where the scope is inert,
but hooks reading config/env now see the drawer's HERMES_HOME.
4. LOW — ty warnings: env Optional asserts before subscript/membership,
fastapi import replaced with web_server.HTTPException re-use.
298 tests green across the four affected suites; tsc -b + vite build
green; aux scoping E2E-verified with real imports.
