feat(windows uninstall): clean up User env, PATH, Scheduled Task, and portable tooling

Browse source 
`hermes uninstall` was POSIX-only.  On Windows it would leave four classes
of installer debris behind that the user had to scrub manually:

1. Scheduled Task and/or Startup-folder .cmd entry that installer.ps1
   dropped for `hermes gateway install`.  Left running at next logon
   even after uninstall, pointing at deleted code paths.
2. User-scope PATH entries for the Hermes venv, PortableGit (cmd, bin,
   usr\bin), and bundled Node, all written to HKCU\Environment\Path.
3. User-scope env vars HERMES_HOME and HERMES_GIT_BASH_PATH, same
   registry key.
4. PortableGit and Node copies under %LOCALAPPDATA%\hermes\ (~200MB),
   plus gateway-service/ scratch dir.

Fixes:

- `uninstall_gateway_service()` gets a Windows branch that calls into
  `gateway_windows.stop()` + `gateway_windows.uninstall()`, which already
  know how to remove both schtasks entries and Startup-folder .cmd files
  and how to stop any running detached pythonw gateway.
- `remove_path_from_windows_registry(hermes_home)` reads HKCU\Environment
  via winreg, strips any PATH entry whose path-prefix matches the
  installer-owned markers (\hermes-agent, \git, \node, \venv under the
  current HERMES_HOME), and writes the cleaned value back.  Preserves
  REG_EXPAND_SZ vs REG_SZ so unexpanded %VARS% in the user's PATH
  survive.  No PowerShell subprocess, no fragile `reg query` parsing.
- `remove_hermes_env_vars_windows()` deletes HERMES_HOME and
  HERMES_GIT_BASH_PATH from the same key.
- `remove_portable_tooling_windows(hermes_home)` rmtree's
  `hermes_home/git`, `hermes_home/node`, `hermes_home/gateway-service`
  — they're installer artifacts, not user data, so they get removed in
  BOTH "keep data" and "full uninstall" modes.

Wired these into `run_uninstall()` guarded by `_is_windows()` so
POSIX paths are untouched.  Also fixed the closing "Reload your shell"
footer to point Windows users at opening a new terminal (PATH changes
don't propagate into the current PowerShell session) with the
PowerShell install one-liner instead of bash's curl-pipe.

Verified on Delta-1 (Windows 10) via preview script: correctly
identifies 4 Hermes-installed PATH entries out of 13 total to remove,
leaves Python/LM Studio/ripgrep/ffmpeg/winget entries alone.

# ============================================================================
# Windows-specific uninstall helpers
# ============================================================================
#
# The installer (``scripts/install.ps1``) does four Windows-only things that
# ``remove_path_from_shell_configs`` / ``remove_wrapper_script`` don't cover:
#
# 1. Sets User-scope env vars ``HERMES_HOME`` and ``HERMES_GIT_BASH_PATH``
# via ``[Environment]::SetEnvironmentVariable(..., "User")``. These
# don't live in ~/.bashrc — they're in the Windows registry at
# HKCU\Environment.
# 2. Prepends to User-scope ``PATH`` (same registry location) entries
# like ``%LOCALAPPDATA%\hermes\git\cmd``, ``%LOCALAPPDATA%\hermes\git\bin``,
# ``%LOCALAPPDATA%\hermes\git\usr\bin``, ``%LOCALAPPDATA%\hermes\node``.
# Again not in any rc file — only accessible via the registry or the
# .NET [Environment] API.
# 3. Downloads PortableGit to ``%LOCALAPPDATA%\hermes\git\`` and Node to
# ``%LOCALAPPDATA%\hermes\node\`` as user-scoped, isolated copies.
# These are ~200MB combined and serve no purpose after uninstall.
# 4. On the ``hermes dashboard`` + gateway paths, drops files into
# ``%LOCALAPPDATA%\hermes\gateway-service\`` and sometimes
# ``%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\`` — the
# latter is handled by ``gateway_windows.uninstall()`` already.
#
# Running a PowerShell one-liner per operation is overkill and fragile on
# locked-down machines (Constrained Language Mode, restricted ExecutionPolicy).
# Direct registry writes via ``winreg`` work without spawning any subprocess
# and apply immediately for new shells (SendMessage WM_SETTINGCHANGE would
# be nicer but requires ctypes and buys us nothing — the user will log out
# or open a new terminal anyway).
