Module resolver 

Active-version resolution for a working directory.

Resolution order for a tool, walking up from the start dir:

1. project config (osdk.toml) [tools] entry
2. .tool-versions entry
3. idiomatic version files (.nvmrc, .node-version, …) — per backend
4. structured project metadata (package.json for Node)
5. user global config [tools] entry

This module is intentionally synchronous and dependency-light so the osdk-shim launcher can use it on the hot path without a tokio runtime.
