Registers PowerShell (.ps1/.psm1/.psd1) in the LSP server registry, spawning PowerShellEditorServices over stdio via a pwsh/powershell host. PSES ships as a GitHub release zip (no npm/go/pip recipe), so it sits in the manual install tier alongside rust-analyzer and clangd. The spawn builder resolves the module bundle from (in order) the lsp.servers.powershell.command override, init bundlePath, the PSES_BUNDLE_PATH env var, or <HERMES_HOME>/lsp/PowerShellEditorServices, then launches Start-EditorServices.ps1 -Stdio with a non-interactive, no-profile host. hermes lsp status/list report it as manual-only until pwsh is present. Docs and tests included.

"""Tests for the PowerShellEditorServices (PSES) server registration.
|
|
|
|
PSES is unusual among the registry entries: it's a PowerShell module
|
|
bundle (GitHub release zip) driven by a ``pwsh`` bootstrap script, not a
|
|
single binary on PATH. These tests cover the registry wiring plus the
|
|
two-prerequisite spawn logic (pwsh host + module bundle).
