Named profiles loaded keybindings only from their own agent dir (~/.omp/profiles/<name>/agent), silently dropping user-level bindings from ~/.omp/agent/keybindings.* — e.g. Backspace remaps under tmux/QTerminal. KeybindingsManager.create now merges the default profile's keybindings under the active profile's, with the profile file overriding per binding. The inherited file is loaded read-only so a named-profile run never writes migration output into the default profile's dir. Documented the exception in docs/config-usage.md. Adopted from PR #4869 (dropped its unrelated workflow-notice.md churn, added the read-only inherited load and its regression test). Fixes #4867 Co-authored-by: roboomp <omp@can.ac>
