Thorsten Bus 9e3e719806 feat(library): add readers + writers for all ProPresenter global libraries and theme bundles
Add full IO support for every global ProPresenter library file plus
theme folders, and extend the existing Labels/Macros readers with
exporters and editable accessors so every supported document is now a
round-trippable, mutable object.

New library readers/writers (each: FileReader, FileWriter, Library
wrapper, element wrapper where applicable, CLI tool, tests, doc/api/*.md):

- Groups          (ProGroupsDocument)        + GroupDefinition
- ClearGroups     (ClearGroupsDocument)      + ClearGroupDefinition
- CCLI            (CCLIDocument)
- Messages        (MessageDocument)          + Message
- Timers          (TimersDocument + Clock)   + Timer
- Stage           (Stage.Document)           + StageLayout
- Workspace       (ProPresenterWorkspace)    + Screen
- Props           (PropDocument)             + Prop
- TestPatterns    (TestPatternDocument)
- Calendar        (new CalendarDocument)     + CalendarEvent
- KeyMappings     (new KeyMappingsDocument)  + KeyMapping
- CommunicationDevices (JSON file)           + CommunicationDevice
- Theme bundles   (Template.Document folder + Assets/) + ThemeBundle/Slide/Asset

Extensions to existing modules:

- LabelsFileWriter; Label and LabelLibrary gain setters, addLabel,
  removeLabel, setColor / setColorHex helpers
- MacrosFileWriter; Macro/MacroCollection/MacroLibrary gain UUID, name,
  color, image_type, image_data, trigger_on_startup setters plus
  add/remove for macros and collections

Two new minimal proto schemas were defined for documents that lacked
upstream definitions:

- proto/calendar.proto   - CalendarDocument with Event entries, raw
  bytes for the action/macro sub-messages so the schema can evolve
- proto/keyMappings.proto - KeyMappingsDocument with ApplicationInfo
  and a forward-looking Mapping message (sample only carries the info)

The Theme file turned out to be a regular Rv\Data\Template\Document, so
no new proto was required for theme content; ThemeBundle layers folder
+ Assets/ handling on top in the same spirit as PresentationBundle.

GroupDefinition is intentionally distinct from the existing Group class
(which wraps song-level CueGroup) to avoid breaking song APIs.

Verified with the full PHPUnit suite: 370 tests, 9200 assertions, all
green; LSP diagnostics clean across src/. The unmodified reference
samples for Labels, Groups, ClearGroups, TestPatterns, Calendar and
KeyMappings round-trip byte-for-byte; the others round-trip with the
same byte length (PHP protobuf is not canonically deterministic but
re-write-after-write stabilises).

doc/INDEX.md, doc/keywords.md and AGENTS.md updated so every new module
is discoverable from the top level.

# CommunicationDevices Library API
> PHP module for reading and writing the global ProPresenter
> `CommunicationDevices` file. Unlike most config files in this project, this
> file is JSON, not protobuf.
## Quick Reference
```php
use ProPresenter\Parser\CommunicationDevice;
use ProPresenter\Parser\CommunicationDevicesFileReader;
use ProPresenter\Parser\CommunicationDevicesFileWriter;
$library = CommunicationDevicesFileReader::read('/path/to/CommunicationDevices');
$library->addDevice((new CommunicationDevice())->setId('device-1')->setName('Router'));
CommunicationDevicesFileWriter::write($library, '/path/to/CommunicationDevices');
```
---
## File Layout
`CommunicationDevices` is a JSON array. The reference sample is `[]`, so the
wrapper preserves arbitrary object fields while exposing forward-looking common
fields: `id`, `name`, `type`, and `address`.
---
## Reading
```php
$library = CommunicationDevicesFileReader::read('/Users/me/.../CommunicationDevices');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
unreadable files or invalid JSON.
---
## CommunicationDevicesLibrary
```php
CommunicationDevicesLibrary::fromJson($json); // CommunicationDevicesLibrary
$library->toJson(); // string
$library->getDocument(); // raw decoded array
$library->getDevices(); // CommunicationDevice[]
$library->addDevice($device); // CommunicationDevice
$library->removeDevice($id); // bool
$library->count(); // int
```
---
## CommunicationDevice
```php
$device->getId();
$device->setId($id);
$device->getName();
$device->setName($name);
$device->getType();
$device->setType($type);
$device->getAddress();
$device->setAddress($address);
$device->toArray(); // full decoded JSON object
```
---
## CLI Tool
```bash
php bin/parse-communication-devices.php /path/to/CommunicationDevices
```
Empty files print a useful `(none configured)` summary.
---
## Key Files
| File | Purpose |
|------|---------|
| `src/CommunicationDevicesLibrary.php` | JSON-array wrapper |
| `src/CommunicationDevice.php` | Single JSON device value object |
| `src/CommunicationDevicesFileReader.php` | Reads and validates JSON |
| `src/CommunicationDevicesFileWriter.php` | Writes compact JSON |
| `bin/parse-communication-devices.php` | CLI summary tool |
---
## Scope Notes
Because only an empty sample is available, unknown JSON fields are preserved in
each device's backing array. The writer uses compact JSON with unescaped
slashes / Unicode for stable semantic round trips.
