Windows installer: user-owned config (APPDATA, no admin), removed nssm service, added user-run launcher. Build script now bundles ZIP: linux installer.sh + windows installer.exe + chrome-extension (from separate repo).

- Implement Option B: Wine-based cross-compilation for Windows .exe via PyInstaller
- NSIS installer with custom configuration page matching Linux installer prompts
  (Gateway URL, Node name, Gateway token)
- Single-file bundles: hermes-node-agent.exe (~45MB), hermes-node-manager.exe (~7MB)
- Config saved to C:\ProgramData\HermesNode\config.json
- Auto-registers as Windows service via NSSM
- Includes build-all.sh, README_BUILD.md, release script
- Update deploy/windows script to fix Windows path separator

- Add Linux installer (self-contained bash script)

- Add Windows build script (NSIS + Python embeddable)

- Installers produce fully offline-capable agents

  - Removed 102 lines of orphaned duplicate PosixComputerController class
  - Fixed code structure: PosixComputerController defined only once (lines 198-267)
  - Reduced file size from 658 to 556 lines

  - Added .gitignore for Python/Windows artifacts:
    * __pycache__/ and *.pyc
    * venv/, build/, dist/
    * *.bak, *.backup
    * windows/build/, windows/Output/
    * IDE files (.vscode, .idea)

  - Removed __pycache__ from git staging (no longer tracked)

Documentation already present in README.md and windows/README.md.

The Chrome browser extension now lives in its own repository:
git@git.nexlab.net:lisa/hermes-node-chrome.git

This keeps the node-agent repo focused on the core agent functionality.

Added complete Windows deployment capability:

  - windows/agent-manager.py: System tray GUI application
    * Configuration editor (no manual JSON editing)
    * Log viewer with refresh/tail
    * Service management (start/stop/restart)
    * Status monitoring dashboard
    * Windows toast notifications

  - windows/installer.iss: Inno Setup installer script
    * Graphical one-click installer
    * Service registration via NSSM
    * Start menu shortcuts
    * Uninstaller support

  - install-windows.ps1: PowerShell installer (legacy/cli)
    * Automated installation without GUI
    * Service registration (NSSM or Task Scheduler)

  - windows/build.py: Automated build script
    * PyInstaller builds for agent and manager
    * Inno Setup compilation
    * Dependency checking

  - Modified hermes_node_agent.py:
    * Fixed duplicate PosixComputerController class
    * Cleaned up code structure

  - Modified install.sh:
    * Simplified user-friendly output
    * Better error handling

The Windows agent includes:
  * PowerShell-based command execution
  * sexec.ps1 permission system (matches Linux)
  * Windows Service integration (NSSM)
  * Same WebSocket protocol (WSS)

Documentation: WINDOWS_DEPLOYMENT.md, WINDOWS_INSTALL.md

See COMPLETE_DEPLOYMENT.md for full overview.

Hermes Agent integration:
  * Works with plugins/node_gateway.py
  * Same API as Linux nodes
  * hermes node windows-pc exec "command"

Major integration of desktop automation and structured capability reporting for Hermes Node Gateway.
This enables a unified node execution framework with optional tool support that is
automatically detected and advertised.

Features:
- ComputerController class (Linux/X11) using xdotool and import (ImageMagick)
  - Screenshot (full screen, optional path or base64-return)
  - Mouse: move(x,y), click(button), position()
  - Keyboard: type_text(text), key_press(key like 'Return', 'Ctrl+c')
  - Window: active_window() returns focused window info
- Capability-based registration to gateway
  - Agent sends tool list ["exec", "browser_control", "computer_control"] on connect
  - gateway filters tools based on declared capabilities
  - missing PC deps handled: checks for xdotool/import; browser extension presence
- Universal installer updated:
  - Prompts: enable browser control? enable computer control?
  - Optional per-node sexec permissions quick-edit (allow/deny/ask comma patterns)
  - Writes config.json with enable_browser, enable_computer_control and permissions JSON
- Fixes:
  - agent formerly advertised capability key 'browser'; gateway expects 'browser_control' → aligned
  - installers baked agent compressed with base64 in shell script, no external files

Files:
- node-agent/: new ComputerController class; enhanced hermes_node_agent.py
- ~/.hermes/plugins/hermes-node-gateway/: added COMPUTER_CONTROL_SCHEMA + handlers + routing
- install_hermes_node_universal.sh (merged in repo dist/ location)

Node Agent endpoint type: "computer_control" commands (gateway forwards to node agent)
Gateway: registers tool 'computer_control' with schema and executes cc_result responses handled

Deployed nodes can now:
  - Execute shell commands via sexec (preserves existing allow/ask/deny)
  - Control browsers (if extension installed)
  - Control desktop (if X11 + xdotool + ImageMagick installed)

Hermes Gateway plugin now exposes 4 tools:
  node_list, node_status, node_exec, browser_control, computer_control ✓
