"""Regression tests for dashboard profile-scoped skills/toolsets management.

"Set as active" on the Profiles page only flips the sticky ``active_profile``
file (future CLI/gateway runs) — it never retargets the running dashboard
process. Before the ``profile`` parameter existed, toggling a skill after
"activating" a profile silently wrote into the dashboard's own config.
These tests pin the new behavior: reads and writes land in the REQUESTED
profile's HERMES_HOME, and the dashboard's own profile stays untouched.
