fix(harness): resolve runtime paths from project root (#2642)

Browse Source 
* fix(harness): resolve runtime paths from project root

* docs(config): update

* fix(config): address runtime path review feedback

* test(config): fix skills path e2e root

* test(config): cover legacy config fallback when project root lacks config files

Verifies that when DEER_FLOW_PROJECT_ROOT is unset and cwd has no
config.yaml/extensions_config.json, AppConfig and ExtensionsConfig fall back
to the legacy backend/repo-root candidates — the backward-compat path
requested in PR #2642 review.
