PR #14157 added control-plane write-deny against the ACTIVE HERMES_HOME, which is fine in non-profile mode but leaves a gap once a profile is active: HERMES_HOME points at <root>/profiles/<name>, so the global <root>/auth.json + <root>/config.yaml + <root>/webhook_subscriptions.json + <root>/mcp-tokens/ remain writable. Same shape as the .env gap PR #15981 closed via _hermes_root_path(). Apply the same widening pattern here. The control-file/mcp-tokens check now iterates BOTH _hermes_home_path() and _hermes_root_path() (dedupes when they coincide in non-profile mode). Also tightens the mcp-tokens check from "startswith dir + os.sep" to "==dir OR startswith dir + os.sep" so writing the directory entry itself is blocked, not just files inside. Regression tests cover both protections in a real profile-mode layout (<tmp>/hermes/profiles/coder as HERMES_HOME, <tmp>/hermes as root).
