func DetectVersion ¶

func DetectVersion(dir string) (string, error)

DetectVersion detects the Node.js version for the given directory. It checks, in order:

1. .lerd.yaml node_version field (explicit lerd override)
2. .nvmrc
3. .node-version
4. package.json engines.node
5. global config default

func ListInstalled ¶ added in v1.23.0

func ListInstalled() []string

ListInstalled returns every Node major version installed under fnm, in the order fnm reports them. Empty when fnm isn't on disk or the user has no versions installed. Centralises the parsing previously duplicated in internal/ui/server.go and internal/mcp/server.go so every surface (web UI, MCP, TUI) sees the same list with the same dedupe rules.
