Implement self-bootstrapping uv setup to resolve issue #14776 (#14814)

* Implement self-bootstrapping uv setup to resolve issue #14776

This major simplification addresses the Python setup complexity that
has been a barrier for non-developer users deploying Algo VPN.

## Revolutionary User Experience Change

**Before (complex):**
```bash
python3 -m virtualenv --python="$(command -v python3)" .env &&
  source .env/bin/activate &&
  python3 -m pip install -U pip virtualenv &&
  python3 -m pip install -r requirements.txt
./algo
```

**After (simple):**
```bash
./algo
```

## Key Technical Changes

### Core Implementation
- **algo script**: Complete rewrite with automatic uv installation
  - Detects missing uv and installs automatically via curl
  - Cross-platform support (macOS, Linux, Windows)
  - Preserves exact same command interface
  - Uses `uv run ansible-playbook` instead of virtualenv activation

### Documentation Overhaul
- **README.md**: Reduced installation from 4 complex steps to 1 command
- **Platform docs**: Simplified macOS, Windows, Linux, Cloud Shell guides
- **Removed Python installation complexity** from all user-facing docs

### CI/CD Infrastructure Updates
- **5 GitHub Actions workflows** converted from pip to uv
- **Docker builds** updated to use uv instead of virtualenv
- **Legacy test scripts** (3 files) updated for uv compatibility

### Repository Cleanup
- **install.sh**: Updated for cloud-init/bootstrap scenarios
- **algo-showenv.sh**: Updated environment detection for uv
- **pyproject.toml**: Added all dependencies with proper versioning
- **test scripts**: Removed .env references, updated paths

## Benefits Achieved

✅ **Zero-step dependency installation** - uv installs automatically on first run
✅ **Cross-platform consistency** - identical experience on all operating systems
✅ **Automatic Python version management** - uv handles Python 3.11+ requirement
✅ **Familiar interface preserved** - existing `./algo` and `./algo update-users` unchanged
✅ **No breaking changes** - existing users see same commands, same functionality
✅ **Resolves macOS Python compatibility** - works with system Python 3.9 via uv's Python management

* Remove unused uv installation code from PowerShell script

The PowerShell script is purely a WSL wrapper - it doesn't need to

* Improve uv installation feedback and Docker dependency locking

- Track and display which installation method succeeded for uv
- Add --locked flag to Docker uv sync for stricter dependency enforcement
- Users now see "uv installed successfully via Homebrew\!" etc.

This addresses code review feedback about installation transparency
and dependency management strictness.

* Fix setuptools package discovery error during cloud provider dependency installation

The issue occurred when uv tried to install optional dependencies (e.g., [digitalocean])
because setuptools was auto-discovering directories like 'roles', 'library', etc. as
Python packages. Since Algo is an Ansible project, not a Python package, this caused
builds to fail.

Added explicit build-system configuration to pyproject.toml with py-modules = [] to
disable package discovery entirely.

* Fix Jinja2 template syntax error in OpenSSL certificate generation

Removed inline comments from within Jinja2 expressions in the name_constraints_permitted
and name_constraints_excluded fields. Jinja2 doesn't support comments within expressions
using the # character, which was causing template rendering to fail.

Moved explanatory comments outside the Jinja2 expressions to maintain documentation

* Enhance Jinja2 template testing infrastructure

Added comprehensive Jinja2 template testing to catch syntax errors early:

1. Created validate_jinja2_templates.py:
   - Validates all Jinja2 templates for syntax errors
   - Detects inline comments in Jinja2 expressions (the bug we just fixed)
   - Checks for common anti-patterns
   - Provides warnings for style issues
   - Skips templates requiring Ansible runtime context

2. Created test_strongswan_templates.py:
   - Tests all StrongSwan templates with multiple scenarios
   - Tests with IPv4-only, IPv6, DNS hostnames, and legacy OpenSSL
   - Validates template output correctness
   - Skips mobileconfig test that requires complex Ansible runtime

3. Updated .ansible-lint:
   - Enabled jinja[invalid] and jinja[spacing] rules
   - These will catch template errors during linting

4. Added scripts/test-templates.sh:
   - Comprehensive test script that runs all template tests
   - Can be used in CI and locally for validation
   - All tests pass cleanly without false failures
   - Treats spacing issues as warnings, not failures

This testing would have caught the inline comment issue in the OpenSSL
template before it reached production. All tests now pass cleanly.

* Fix StrongSwan CRL reread handler race condition

The ipsec rereadcrls command was failing with exit code 7 when the IPsec
daemon wasn't fully started yet. This is a timing issue that can occur
during initial setup.

Added retry logic to:
1. Wait up to 10 seconds for the IPsec daemon to be ready
2. Check daemon status before attempting CRL operations
3. Gracefully handle the case where daemon isn't ready

Also fixed Python linting issues (whitespace) in test files caught by ruff.

* Fix StrongSwan CRL handler properly without ignoring errors

Instead of ignoring errors (anti-pattern), this fix properly handles the race
condition when StrongSwan restarts:

1. After restarting StrongSwan, wait for port 500 (IKE) to be listening
   - This ensures the daemon is fully ready before proceeding
   - Waits up to 30 seconds with proper timeout handling

2. When reloading CRLs, use Ansible's retry mechanism
   - Retries up to 3 times with 2-second delays
   - Handles transient failures during startup

3. Separated rereadcrls and purgecrls into distinct tasks
   - Better error reporting and debugging
   - Cleaner task organization

This approach ensures the installation works reliably on fresh installs
without hiding potential real errors.

* Fix StrongSwan handlers - handlers cannot be blocks

Ansible handlers cannot be blocks. Fixed by:

1. Making each handler a separate task that can notify the next handler
2. restart strongswan -> notifies -> wait for strongswan
3. rereadcrls -> notifies -> purgecrls

This maintains the proper execution order while conforming to Ansible's
handler constraints. The wait and retry logic is preserved.

🤖 Generated with [Claude Code](https://claude.ai/code)

* Fix StrongSwan CRL handler for fresh installs

The root cause: rereadcrls handler is notified when copying CRL files
during certificate generation, which happens BEFORE StrongSwan is installed
and started on fresh installs.

The fix:
1. Check if StrongSwan service is actually running before attempting CRL reload
2. If not running, skip reload (not needed - StrongSwan will load CRLs on start)
3. If running, attempt reload with retries

This handles both scenarios:
- Fresh install: StrongSwan not yet running, skip reload
- Updates: StrongSwan running, reload CRLs properly

Also removed the wait_for port 500 which was failing because StrongSwan
doesn't bind to localhost.
