Add mods/sdk/ with the kindred_sdk Python package providing a stable
API layer for addon integration with Kindred Create platform features.
Modules:
- context: editing context/overlay registration wrappers
- theme: YAML-driven palette system (Catppuccin Mocha)
- origin: FileOrigin registration helpers
- dock: deferred dock panel registration
- compat: version detection utilities
The SDK loads at priority 0 (before all other addons) via the existing
manifest-driven loader. Theme colors are defined in a single YAML
palette file instead of hardcoded Python dicts, enabling future theme
support and eliminating color duplication across addons.
Closes#249
Add <kindred> elements to ztools (priority=50) and silo (priority=60)
package.xml files declaring min_create_version, load_priority,
pure_python, and context metadata.
Fix addon_loader.py topological sort to use level-by-level processing
with (priority, name) sorting within each level, replacing
static_order() which did not guarantee deterministic ordering.
Add docs/src/development/package-xml-schema.md documenting the full
field reference, schema example, and backward compatibility notes.
Closes#252
Wires DAG extraction into Silo_Save and Silo_Commit commands.
After successful file upload, extracts the feature DAG and pushes
it to the server. Failures warn but never block the save.
Closes#216
Adds push_dag() and get_dag() to SiloClient:
- push_dag: PUT /api/items/{pn}/dag with nodes + edges
- get_dag: GET /api/items/{pn}/dag with optional revision filter
Closes#215
Replace 2-color Base→Crust gradient with 3-color Overlay0→Mantle→Overlay0
gradient in both KindredCreate preference pack and CatppuccinMocha theme.
Enables UseBackgroundColorMid for the 3-color effect.
