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.

# TestPatterns Library API
> PHP module for reading and writing the global ProPresenter `TestPatterns` file
> (raw protobuf, no extension), including selected test-pattern state and saved
> pattern definitions.
## Quick Reference
```php
use ProPresenter\Parser\TestPatternsFileReader;
use ProPresenter\Parser\TestPatternsFileWriter;
$library = TestPatternsFileReader::read('/path/to/TestPatterns');
$library->getDisplayLocation(); // 3
$library->getSpecificScreenUuid(); // "BCDE1115-..."
$library->getPatterns(); // TestPatternData[]
TestPatternsFileWriter::write($library, '/path/to/TestPatterns');
```
---
## File Layout
The `TestPatterns` file is the protobuf-serialised
[`TestPatternDocument`](../../proto/testPattern.proto):
| Field | Type | Description |
|-------|------|-------------|
| `state` | `TestPatternDocument.TestPatternStateData` | Current test-pattern display state |
| `patterns` | repeated `TestPatternDocument.TestPatternData` | Saved pattern definitions |
`TestPatternStateData` includes selected pattern UUID/name, display location,
specific screen UUID, identify-screen flag, logo type, and optional user logo.
---
## Reading
```php
use ProPresenter\Parser\TestPatternsFileReader;
$library = TestPatternsFileReader::read('/Users/me/.../TestPatterns');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
empty / unreadable files.
---
## TestPatternsLibrary
Top-level wrapper around `Rv\Data\TestPatternDocument`. Indexes saved pattern
definitions by UUID (case-insensitive) and localization key.
```php
$library->getState();
$library->setState($stateOrNull);
$library->getSelectedPatternUuid();
$library->getSelectedPatternNameLocalizationKey();
$library->getDisplayLocation();
$library->getSpecificScreenUuid();
$library->getPatterns();
$library->count();
$library->getPatternByUuid('...');
$library->getPatternByName('Test Pattern');
$library->addPattern('Test Pattern', 'UUID');
$library->removePattern('UUID');
$library->getDocument(); // \Rv\Data\TestPatternDocument
```
---
## CLI Tool
```bash
php bin/parse-test-patterns.php /path/to/TestPatterns
```
Output:
```
TestPatterns (0):
State: selected=(none) :: name=(none) :: display_location=3 :: screen=BCDE1115-AD40-4BA4-A33A-BFFE3E87223B
```
---
## Key Files
| File | Purpose |
|------|---------|
| `src/TestPatternsLibrary.php` | Document-level wrapper with state accessors |
| `src/TestPatternsFileReader.php` | Reads the `TestPatterns` file |
| `src/TestPatternsFileWriter.php` | Writes the `TestPatterns` file |
| `bin/parse-test-patterns.php` | CLI tool |
| `proto/testPattern.proto` | Protobuf schema |
| `generated/Rv/Data/TestPatternDocument.php` | Generated message class |
---
## Scope Notes
The wrapper exposes `TestPatternData` and `TestPatternStateData` protobufs
directly. It does not render test patterns or interpret nested property oneofs.
