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.

# Messages Library API
> PHP module for reading and writing the global ProPresenter `Messages` file
> (raw protobuf, no extension) and exposing each message definition.
## Quick Reference
```php
use ProPresenter\Parser\MessagesFileReader;
use ProPresenter\Parser\MessagesFileWriter;
$library = MessagesFileReader::read('/path/to/Messages');
foreach ($library->getMessages() as $message) {
$message->getTitle();
$message->getUuid();
$message->getMessageText();
}
$library->addMessage('Lobby Notice', '11111111-1111-1111-1111-111111111111');
MessagesFileWriter::write($library, '/path/to/Messages');
```
---
## File Layout
The `Messages` file is the protobuf-serialised
[`MessageDocument`](../../proto/messages.proto):
| Field | Type | Description |
|-------|------|-------------|
| `application_info` | `ApplicationInfo` | ProPresenter metadata |
| `messages` | repeated `Message` | Message definitions in document order |
---
## Reading
```php
$library = MessagesFileReader::read('/Users/me/.../Messages');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
empty / unreadable files.
---
## MessageLibrary
```php
$library->getMessages(); // Message[]
$library->count(); // int
$library->getMessageByUuid($uuid); // ?Message (case-insensitive)
$library->getMessageByName($title); // ?Message (case-sensitive title)
$library->addMessage($title, $uuid); // Message
$library->removeMessage($uuid); // bool
$library->getApplicationInfo(); // ?\Rv\Data\ApplicationInfo
$library->getDocument(); // \Rv\Data\MessageDocument
```
---
## Message
```php
$message->getUuid();
$message->setUuid($uuid);
$message->getTitle();
$message->setTitle($title);
$message->getTimeToRemove();
$message->setTimeToRemove($seconds);
$message->isVisibleOnNetwork();
$message->setVisibleOnNetwork(true);
$message->getMessageText();
$message->setMessageText($text);
$message->getClearType();
$message->setClearType($enumValue);
$message->getTokens(); // raw repeated Token protos
$message->getProto(); // \Rv\Data\Message
```
---
## CLI Tool
```bash
php bin/parse-messages.php /path/to/Messages
```
---
## Key Files
| File | Purpose |
|------|---------|
| `src/MessageLibrary.php` | Document wrapper with title / UUID indexes |
| `src/Message.php` | Single message wrapper |
| `src/MessagesFileReader.php` | Reads the `Messages` file |
| `src/MessagesFileWriter.php` | Writes the `Messages` file |
| `bin/parse-messages.php` | CLI summary tool |
| `generated/Rv/Data/MessageDocument.php` | Generated document class |
---
## Scope Notes
Tokens and token values are preserved as raw generated protobuf objects. The
wrapper exposes them for advanced callers but does not interpret template
rendering semantics.
