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.

# Calendar Library API
> PHP module for reading and writing the global ProPresenter `Calendar` file
> (raw protobuf, no extension) and preserving scheduled macro events.
## Quick Reference
```php
use ProPresenter\Parser\CalendarFileReader;
$library = CalendarFileReader::read('/path/to/Calendar');
foreach ($library->getEvents() as $event) {
$event->getName();
$event->getStartTimeSeconds();
$event->getActionData(); // raw bytes
}
```
---
## File Layout
The `Calendar` file is the protobuf-serialised
[`CalendarDocument`](../../proto/calendar.proto):
| Field | Type | Description |
|-------|------|-------------|
| `events` | repeated `CalendarDocument.Event` | Scheduled events |
| `mode` | `uint32` | Opaque document mode/source flag |
Each event includes UUID, name, start/end timestamps, opaque `flags`, and two
raw bytes fields: `action_data` (field 8) and `macro_data` (field 9). Those
bytes are intentionally not decoded by this wrapper.
---
## Reading
```php
$library = CalendarFileReader::read('/Users/me/.../Calendar');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
empty / unreadable files.
---
## CalendarLibrary
```php
$library->getEvents(); // CalendarEvent[]
$library->count(); // int
$library->getEventByUuid($uuid); // ?CalendarEvent (case-insensitive)
$library->getEventByName($name); // ?CalendarEvent
$library->addEvent($name, $uuid); // CalendarEvent
$library->removeEvent($uuid); // bool
$library->getMode(); // int
$library->setMode(1); // void
$library->getDocument(); // \Rv\Data\CalendarDocument
```
---
## CalendarEvent
```php
$event->getUuid();
$event->setUuid($uuid);
$event->getName();
$event->setName($name);
$event->getStartTime();
$event->setStartTime($timestamp);
$event->getStartTimeSeconds();
$event->setStartTimeSeconds($seconds);
$event->getEndTime();
$event->getEndTimeSeconds();
$event->getFlags();
$event->setFlags($bytes);
$event->getActionData(); // raw protobuf bytes
$event->setActionData($bytes);
$event->getMacroData(); // raw protobuf bytes
$event->setMacroData($bytes);
$event->getProto();
```
---
## CLI Tool
```bash
php bin/parse-calendar.php /path/to/Calendar
```
---
## Key Files
| File | Purpose |
|------|---------|
| `src/CalendarLibrary.php` | Document wrapper with UUID / name indexes |
| `src/CalendarEvent.php` | Single event wrapper |
| `src/CalendarFileReader.php` | Reads the `Calendar` file |
| `src/CalendarFileWriter.php` | Writes the `Calendar` file |
| `bin/parse-calendar.php` | CLI summary tool |
| `proto/calendar.proto` | Protobuf schema |
| `generated/Rv/Data/CalendarDocument.php` | Generated document class |
---
## Scope Notes
`action_data` and `macro_data` are raw protobuf byte strings. They are exposed
directly for byte-preserving edits and round trips; semantic decoding belongs in
a future schema-specific module.
