feat(pwsh): add the pwsh-local executor and the pwsh tool
Windows-native execution foundation: PwshLocalExecutor implements the bash executor seam over ctx.subprocess (pwsh -NoLogo -NoProfile -NonInteractive -Command, one argv element, no quoting layer; resolvePwshPath probes PowerShell 7 / PATH / Windows PowerShell 5.1 as a pure function), and tool-pwsh is the minimal PowerShell-dialect model-facing tool over ctx.bash (foreground only, managed DSH_* env, timeout/signal/exit markers, terminal and generic presenters). Both packages carry full suites (real pwsh, self-skipping without it) at per-file 100% coverage; vitest's Windows exclusion narrows from packages/bash/* to the bash-requiring packages so the pwsh suites run natively on Windows too. The CLI gains the workspace deps and tsconfig projects without mounting either plugin; the Windows-default roadmap is recorded as a proposed Agent Note.

Execute a PowerShell command (`pwsh -Command`) and return its stdout/stderr. Each call runs in a fresh pwsh process: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Paths use native Windows form (`C:\...`); read environment variables with `$env:NAME`. Non-zero exits are reported as `[exit code: N]`. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available.
