Usage:
  install hook for one repo:
    ./scripts/install-anythingllm-post-merge-hook.sh <path-to-git-repo> [<path-to-smart_ide>]

  install hook for configured project clones:
    ./scripts/install-anythingllm-post-merge-hook.sh --all [--smart-ide-root <path>]
    ./scripts/install-anythingllm-post-merge-hook.sh --project <id> [--smart-ide-root <path>]

Notes:
  - Project clones are resolved from smart_ide `projects/<id>/conf.json` -> `project_path`.
  - The hook sources `${HOME}/.config/4nk/anythingllm-sync.env` if present.
