Address latest review comments from sky5454 in PR #2654.
scripts/copydir.go:
- Improve repository root detection in a safer, more deterministic way.
- Prefer locating repo root from the script source path via runtime.Caller(), then fallback to upward search from current working directory.
- Replace .git-only root detection with repository anchor validation: go.sum, LICENSE, and .github must exist.
- Keep \ placeholder expansion and existing in-repo path guards.
- Preserve destination safety check to prevent deleting/copying to repo root.
web/backend/api:
- Rename applyLauncherWindowsProcAttrs() to applyLauncherProcAttrs() to expose a platform-independent interface name.
- Keep platform-specific behavior split by build tags: windows keeps HideWindow SysProcAttr setup, non-windows remains no-op.
- Update gateway startup path to call the renamed helper.
Why:
- Follow reviewer feedback to avoid relying on .git detection alone and prefer runtime/file-anchor based repository location.
- Improve naming clarity by making cross-platform interfaces generic while preserving OS-specific implementation details internally.
Validation:
- go test ./cmd/picoclaw/internal/onboard
- go test ./web/backend/api
