.SYNOPSIS
  Bootstrap the SimReady Pipeline Bot runtime dependencies.

.DESCRIPTION
  Idempotent. Run once on a fresh machine, or re-run any time to fix a
  missing dependency. Creates a Python venv, clones the foundation + SDK
  repos, and pip-installs everything the /simready-report skill needs.

  The foundation specs are *not* editable-installed any more. validate.py
  now defaults to populating the OAV registries via the simready-validate
  CLI loader against on-disk paths under the foundations checkout.
  Avoids the `repo usd_profiles_codegen` codegen step (which depends on
  internal packman tooling not shipped in the public GitHub repo) and the
  Forced-include trap in nv_core/sr_specs/pyproject.toml.

  Layout produced (all under -DepsRoot, default $env:LOCALAPPDATA\simready):

    <DepsRoot>\
      ├── venv\                     # Python venv (created if missing)
      ├── simready_foundations\     # cloned from NVIDIA GitHub
      └── simready-oem-sdk-poc\     # cloned from NVIDIA-dev GitHub

  After a successful install the script writes three User-level environment
  variables so the /simready-report skill can locate everything from any shell:

    SIMREADY_PYTHON           = <DepsRoot>\venv\Scripts\python.exe
    SIMREADY_FOUNDATIONS_PATH = <DepsRoot>\simready_foundations
    SIMREADY_SDK_PATH         = <DepsRoot>\simready-oem-sdk-poc

  Override the location with -DepsRoot, e.g.:
    .\bootstrap.ps1 -DepsRoot D:\simready-deps

  Already have these repos checked out elsewhere? Skip this script and
  set the two env vars manually.

  Optional (not bootstrapped): a `usd_validation_dashboard_final\` clone —
  used only to copy Sphinx _static\ assets into rendered doc pages. If
  absent, the dashboard's doc pages fall back to minimal inline styling.

.NOTES
  - Reversible: the dirs created here are safe to delete; rerun this
    script to re-create them. The two env vars can be cleared with
    `[Environment]::SetEnvironmentVariable("SIMREADY_FOUNDATIONS_PATH", $null, "User")`.
  - Requires: git, python (3.11+ recommended), and access to
    github.com/NVIDIA + github.com/NVIDIA-dev (creds via the user's
    existing git/gh auth).
  - Never elevates / never modifies system PATH.
