Function uninstall_prefixed

atomic-agent/src/hooks/manifest.rs:189–215

Remove hook commands identified by `command_prefix` from `hooks_key` in `target`, without needing the original manifest file. Used by receipt-driven integration uninstalls, where the receipt records `(target, hooks_key, command_prefix)` but the package may no longer exist on disk.
