refactor-servers-workstations-shell-monitoring (#4)
### Summary

This PR refactors the playbook layout to reduce duplication and make host intent clearer (servers vs workstations), splits monitoring by host type, and restores full Zsh setup for developers while keeping servers aliases-only.

### Key changes

- **New playbooks**
  - `playbooks/servers.yml`: baseline for server-class hosts (no desktop apps)
  - `playbooks/workstations.yml`: baseline for dev/desktop/local + **desktop apps only on `desktop` group**

- **Monitoring split**
  - `roles/monitoring_server`: server monitoring + intrusion prevention (includes `fail2ban`, sysstat)
  - `roles/monitoring_desktop`: desktop-oriented monitoring tooling
  - Updated playbooks to use the correct monitoring role per host type

- **Shell role: server-safe + developer-friendly**
  - `roles/shell` now supports two modes:
    - `shell_mode: minimal` (default): aliases-only, does not overwrite `.zshrc`
    - `shell_mode: full`: installs Oh My Zsh + Powerlevel10k + plugins and deploys a managed `.zshrc`
  - `playbooks/development.yml` and `playbooks/workstations.yml` use `shell_mode: full`
  - `playbooks/servers.yml` remains **aliases-only**

- **Applications**
  - Applications role runs only on `desktop` group (via `workstations.yml`)
  - Removed Brave installs/repo management
  - Added **CopyQ** to desktop apps (`applications_desktop_packages`)

- **Docs + architecture**
  - Added canonical doc tree under `project-docs/` (overview/architecture/standards/workflow/decisions)
  - Consolidated architecture docs: `docs/reference/architecture.md` is now a pointer to `project-docs/architecture.md`
  - Fixed broken doc links by adding the missing referenced pages under `docs/`

### Behavior changes (important)

- Desktop GUI apps install **only** on the `desktop` inventory group (not on servers, not on dev VMs unless they are in `desktop`).
- Dev/workstation Zsh is now provisioned in **full mode** (managed `.zshrc` + p10k).

### How to test (local CI parity)

```bash
make test
npm test
```

Optional dry runs (interactive sudo may be required):

```bash
make check
make check-local
```

### Rollout guidance

- Apply to a single host first:
  - Workstations: `make workstations HOST=<devhost>`
  - Servers: `make servers HOST=<serverhost>`
- Then expand to group runs.

# Role: development
## Description
Installs core development tools and utilities for software development. This role provides a lightweight foundation for coding without heavy data science dependencies.
**For data science tools (Anaconda, Jupyter, R), see the `datascience` role.**
## Requirements
- Ansible 2.9+
- Debian/Ubuntu systems
- Root or sudo access
## Installed Components
### Development Tools
- **git**: Version control system
- **build-essential**: C/C++ compilation tools (gcc, g++, make)
- **python3**: Python 3 interpreter
- **python3-pip**: Python package manager
### Node.js
- **Node.js 22.x**: Latest LTS from NodeSource
- **npm**: Node package manager (included with Node.js)
- Configured from official NodeSource repository
## Variables
### Core Settings
| Variable | Default | Description |
|----------|---------|-------------|
| `development_packages` | See defaults | Base packages installed by the role |
## Dependencies
- `base` role (for core utilities)
## Example Playbook
### Basic Installation
```yaml
- hosts: developers
roles:
- role: development
```
### Customize packages
```yaml
- hosts: developers
roles:
- role: development
vars:
development_packages:
- git
- build-essential
- python3
- python3-pip
```
## Usage
```bash
# Install on specific host
make dev HOST=dev01
# Install only development tools (skip other roles)
ansible-playbook playbooks/development.yml --limit dev01 --tags development
```
## Tags
- `development`, `dev`: All development tasks
## Post-Installation
### Verify Installations
```bash
git --version
node --version
npm --version
python3 --version
```
### Node.js Usage
```bash
# Install packages globally
npm install -g <package>
# Check Node.js version
node --version # Should show v22.x
```
## Performance Notes
### Installation Time
- **Base packages**: 1-2 minutes
- **Node.js**: 1-2 minutes
- **Total**: ~3-5 minutes
### Disk Space
- **Node.js + npm**: ~100MB
- **Build tools**: ~50MB
- **Total**: ~150MB
## Integration
### With Data Science Role
```yaml
- hosts: datascience_workstation
roles:
- role: development # Core dev tools
- role: datascience # Anaconda, Jupyter, R
```
### With Docker
```yaml
- hosts: fullstack_dev
roles:
- role: development
- role: docker
```
## Troubleshooting
### Node.js Version Issues
If Node.js doesn't upgrade to v22:
```bash
# Check current version
node --version
# Force reinstall
apt-get remove nodejs
# Re-run playbook
```
## Notes
- Node.js 22 is the current LTS version
- NodeSource repository is configured for automatic updates
- Build tools (gcc, make) are essential for npm native modules
- Python 3 is included for development scripts
- All installations are idempotent (safe to re-run)
## Comparison with Data Science Role
| Component | Development Role | Data Science Role |
|-----------|------------------|-------------------|
| Git | ✅ | - |
| Node.js | ✅ | - |
| Build Tools | ✅ | - |
| Anaconda | ❌ | ✅ |
| Jupyter | ❌ | ✅ |
| R Language | ❌ | ✅ |
| Install Time | ~10 min | ~30-60 min |
| Disk Space | ~150MB | ~3GB |
**Recommendation**: Use `development` role for general coding. Add `datascience` role only when needed for data analysis/ML work.
