feat: Windows native support via Git Bash

- Add scripts/install.cmd batch wrapper for CMD users (delegates to install.ps1)
- Add _find_shell() in local.py: detects Git Bash on Windows via
  HERMES_GIT_BASH_PATH env var, shutil.which, or common install paths
  (same pattern as Claude Code's CLAUDE_CODE_GIT_BASH_PATH)
- Use _find_shell() in process_registry.py for background processes
- Fix hermes_cli/gateway.py: use wmic instead of ps aux on Windows,
  skip SIGKILL (doesn't exist on Windows), fix venv path
  (Scripts/python.exe vs bin/python)
- Update README with three install commands (Linux/macOS, PowerShell, CMD)
  and Windows native documentation

Requires Git for Windows, which bundles bash.exe. The terminal tool
transparently uses Git Bash for shell commands regardless of whether
the user launched hermes from PowerShell or CMD.

 The installer will:
 - Install [uv](https://docs.astral.sh/uv/) (fast Python package manager) if not present
 - Install Python 3.11 via uv if not already available (no sudo needed)
 - Clone to `~/.hermes/hermes-agent` (with submodules: mini-swe-agent, tinker-atropos)
 - Create a virtual environment with Python 3.11
 - Install all dependencies and submodule packages
-- Symlink `hermes` into `~/.local/bin` so it works globally (no venv activation needed)
