<objective>
Create the script generator module and install.ps1 Jinja2 template with full correctness guards.
Purpose: The install script is the most complex of the three scripts (WOW64, UAC, pnputil two-step, idempotency, duplex mapping). Building it first with TDD ensures all edge cases are covered before the simpler templates.
Output: `script_generator.py` with `render_install()`, `install.ps1.j2` template, and passing unit tests.

<behavior>
- render_install(printer_name, ip_address, port_name, driver_name, inf_filename, duplex_mode, color_mode, paper_size, collate) returns a string containing valid PowerShell
- Output contains WOW64 guard: `$env:PROCESSOR_ARCHITECTURE -eq "x86"` and `SysNative` relaunch as the FIRST executable block
- Output contains SYSTEM/admin detection: `WindowsIdentity::GetCurrent()`, `IsSystem`, `IsInRole(Administrator)`, `Start-Process -Verb Runas`
- Output contains pnputil two-step: `pnputil.exe /add-driver "$PSScriptRoot\drivers\{inf_filename}" /install` then `Add-PrinterDriver -Name "{driver_name}"`
- Output contains idempotent port creation: `Get-PrinterPort` check before `Add-PrinterPort`
- Output contains idempotent printer creation: `Get-Printer` check before `Add-Printer`
- Output contains `Set-PrintConfiguration` with translated duplex: "LongEdge" -> "TwoSidedLongEdge", "ShortEdge" -> "TwoSidedShortEdge", "OneSided" -> "OneSided"
- Output contains correct boolean rendering: color_mode=True -> `$true`, color_mode=False -> `$false`
- Output contains paper size and collate values
- Script uses proper quoting for printer name, port name, driver name (double-quoted in PS)
</behavior>
<implementation>
**RED phase — write tests first in tests/test_script_generator.py:**
1. Create `imptune/templates/scripts/` directory (empty, needed for Jinja2 loader)
2. Write tests that import `render_install` from `imptune.generators.script_generator` and assert on rendered output:
- `test_render_install_contains_pnputil`: assert `pnputil.exe /add-driver` and `Add-PrinterDriver` in output
- `test_render_install_print_config`: assert `Set-PrintConfiguration` with `-DuplexingMode TwoSidedLongEdge` when duplex_mode="LongEdge"
- `test_render_install_wow64_guard`: assert `PROCESSOR_ARCHITECTURE` and `SysNative` in output
- `test_render_install_uac_guard`: assert `IsSystem` and `Start-Process` and `-Verb Runas` in output
- `test_render_install_idempotency`: assert `Get-PrinterPort` and `Get-Printer` checks before add operations
- `test_render_install_booleans`: assert `$true` / `$false` for color and collate
3. Run tests — all MUST fail (RED)
**GREEN phase — implement:**
4. Create `imptune/generators/script_generator.py`:
- Module-level Jinja2 Environment with `FileSystemLoader` pointing to `imptune/templates/scripts/`
- `trim_blocks=True`, `lstrip_blocks=True`, `keep_trailing_newline=True`
- `_duplex_map` dict: `{"OneSided": "OneSided", "LongEdge": "TwoSidedLongEdge", "ShortEdge": "TwoSidedShortEdge"}`
- `render_install(printer_name, ip_address, port_name, driver_name, inf_filename, duplex_mode, color_mode, paper_size, collate) -> str`
- Translates duplex_mode via `_duplex_map`
- Converts color_mode/collate bools to `"true"` / `"false"` (lowercase, template adds `$` prefix)
- Calls `_env.get_template("install.ps1.j2").render(...)` with all variables
- Use plain string parameters (not ORM objects) so the function is testable without DB
5. Create `imptune/templates/scripts/install.ps1.j2`:
Template structure (in this exact order):
```
# Header comment: Generated by ImpTune, printer name, install command hint
# WOW64 Guard (FIRST executable block)
if ($env:PROCESSOR_ARCHITECTURE -eq "x86" -and $env:PROCESSOR_ARCHITEW6432) { ... relaunch 64-bit ... exit }
# SYSTEM/Admin check + UAC elevation
$id = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$isSystem = $id.IsSystem
$isAdmin = ... IsInRole(Administrator)
if (-not $isSystem -and -not $isAdmin) { Start-Process -Verb Runas ... exit }
# pnputil driver staging
pnputil.exe /add-driver "$PSScriptRoot\drivers\{{ inf_filename }}" /install
# Add-PrinterDriver
Add-PrinterDriver -Name "{{ driver_name }}"
# Idempotent port creation
if (-not (Get-PrinterPort -Name "{{ port_name }}" -ErrorAction SilentlyContinue)) { Add-PrinterPort ... }
# Idempotent printer creation
if (-not (Get-Printer -Name "{{ printer_name }}" -ErrorAction SilentlyContinue)) { Add-Printer ... }
# Set-PrintConfiguration
Set-PrintConfiguration -PrinterName "{{ printer_name }}" -DuplexingMode {{ duplex_mode }} -Color ${{ color }} -PaperSize {{ paper_size }} -Collate ${{ collate }}
```
6. Run tests — all MUST pass (GREEN)
**Important notes:**
- Use plain string args for render_install, NOT Printer ORM object — keeps tests DB-free
- The `_duplex_map` must translate BEFORE passing to template (template receives already-mapped value)
- Boolean values: pass as lowercase string `"true"` / `"false"` so template renders `$true` / `$false` with `${{ color }}`
- Template must use `{{ }}` for all variable interpolation — no `{% set %}` for simple values
- All PowerShell string parameters (printer_name, port_name, driver_name) must be double-quoted in the template
</implementation>
</feature>

All 6+ tests pass. Rendered install script contains all required blocks in correct order.
</verification>
<success_criteria>
- render_install() produces complete PowerShell install script
- WOW64 guard appears before any other logic
- UAC self-elevation skips when SYSTEM
- Duplex mode values correctly translated (LongEdge -> TwoSidedLongEdge)
- All add operations wrapped in idempotency checks
- All unit tests pass

<objective>
Add uninstall and detection templates, then wire all three scripts to downloadable API endpoints.
Purpose: Completes the script generation phase by adding the two simpler templates and exposing all scripts via GET endpoints that the printer detail page (Phase 3) can link to.
Output: `uninstall.ps1.j2`, `detect.ps1.j2`, `scripts.py` router, updated `main.py`, passing integration tests.

</behavior>
<action>
**Tests first (add to existing test_script_generator.py):**
- `test_render_uninstall`: call render_uninstall("Test Printer", "HP Driver", "IP_10.0.0.1"), assert output contains `Remove-Printer -Name "Test Printer"`, `Remove-PrinterDriver -Name "HP Driver"`, `Remove-PrinterPort -Name "IP_10.0.0.1"`, and `-ErrorAction SilentlyContinue` on all three. Assert Remove-Printer appears BEFORE Remove-PrinterDriver (order matters — driver removal fails if printer still references it).
- `test_render_detect`: call render_detect("Test Printer"), assert output contains `Get-Printer -Name "Test Printer"`, `Write-Output`, `exit 0`, `exit 1`.
Run tests — both MUST fail.
**Implement:**
Add `render_uninstall(printer_name, driver_name, port_name) -> str` to `script_generator.py`:
- Gets `uninstall.ps1.j2` template, renders with the three names.
Add `render_detect(printer_name) -> str` to `script_generator.py`:
- Gets `detect.ps1.j2` template, renders with printer_name.
Create `imptune/templates/scripts/uninstall.ps1.j2`:
```
# Header: Generated by ImpTune — Uninstall script for {{ printer_name }}
Remove-Printer -Name "{{ printer_name }}" -ErrorAction SilentlyContinue
Remove-PrinterDriver -Name "{{ driver_name }}" -ErrorAction SilentlyContinue
Remove-PrinterPort -Name "{{ port_name }}" -ErrorAction SilentlyContinue

Create `imptune/api/scripts.py`:
- `router = APIRouter(prefix="/printers")`
- Three GET endpoints: `/{printer_id}/scripts/install`, `/{printer_id}/scripts/uninstall`, `/{printer_id}/scripts/detect`
- Each endpoint:
1. `Printer.get_or_none(Printer.id == printer_id)` — return `PlainTextResponse("Printer not found", status_code=404)` if None
2. Access `printer.driver` — return `PlainTextResponse("No driver assigned", status_code=422)` if driver is None
3. Check `driver.inf_filename` — return `PlainTextResponse("Driver has no INF file", status_code=422)` if None/empty
4. Parse `driver_name = json.loads(driver.driver_desc)[0]` — return 422 if driver_desc is empty/null
5. Call the appropriate render function with plain values extracted from ORM objects
6. Return `PlainTextResponse(content=rendered, headers={"Content-Disposition": 'attachment; filename="{type}.ps1"'})`
- For install endpoint: extract all printer fields + driver fields, call `render_install(printer.name, printer.ip_address, printer.port_name, driver_name, driver.inf_filename, printer.duplex_mode, printer.color_mode, printer.paper_size, printer.collate)`
- For uninstall: call `render_uninstall(printer.name, driver_name, printer.port_name)`
- For detect: call `render_detect(printer.name)`
Update `imptune/main.py`:
- Add `scripts` to import: `from imptune.api import clients, drivers, health, pages, printers, scripts`
- Add `app.include_router(scripts.router)` after existing router registrations
Add integration tests to `tests/test_script_generator.py`:
- `test_install_endpoint`: create Driver + Printer via ORM in test, GET `/printers/{id}/scripts/install`, assert 200 + content contains `pnputil`
- `test_uninstall_endpoint`: same setup, GET `/printers/{id}/scripts/uninstall`, assert 200 + `Remove-Printer`
- `test_detect_endpoint`: same setup, GET `/printers/{id}/scripts/detect`, assert 200 + `Write-Output`
- `test_script_endpoint_missing_printer`: GET `/printers/9999/scripts/install`, assert 404
- `test_script_endpoint_no_driver`: create Printer without driver FK, GET install, assert 422
For integration tests, use the `client` fixture from conftest.py. Create test data via ORM:
```python
from imptune.db.models import Driver, Printer
driver = Driver.create(sha256="abc123", original_filename="test.zip", size_bytes=100,
driver_desc='["Test Driver"]', inf_filename="test.inf")
