Respect existing installPath and plugins.load.paths in installer (#1116)

The installer hardcoded ~/.openclaw/extensions/claude-mem as the target.
Users who moved the extension to a custom path (e.g. workspace
extensions via plugins.load.paths) would have their setup broken on
update. Now resolve_extension_dir() checks the OpenClaw config for an
existing installPath or load.paths entry before falling back to the
default.
