The Angular language server (ngserver) was not found when Node and global npm packages came from a version manager (nvm, fnm, volta, asdf, mise) whose bin directories are not on the GUI app's PATH. Tool lookup now searches those directories too through a shared ide-core tool_path module used by the LSP launcher, SDK queries and tool detection; explicit relative commands resolve against the project root, empty PATH entries are ignored, and a non-executable file earlier on PATH no longer shadows the real command. The process query test that flaked under load now uses a generous deadline for the success case, with the timeout covered by a separate test of a child that never exits.
