[good first issue] feat(hermes): support Windows native setup

[PorunC]

Description | 描述

Adds Windows-native Hermes setup support for memory-tencentdb:

• adds a Windows batch installer that checks prerequisites, installs Gateway dependencies, copies the Hermes provider, writes Hermes env/config hints, starts the Gateway, and verifies /health
• replaces the Bash-only npm postinstall hook with a cross-platform Node wrapper that skips OpenClaw patching on Windows/Hermes installs
• updates the Hermes provider supervisor to launch the Gateway through Windows-compatible command handling and mirror Gateway env vars
• documents Windows native Hermes setup in the root READMEs and Hermes provider README
