- Create FusionProvider component that initializes TaskStore and provides it via React context - Add useFusion() hook for accessing TaskStore and project path from any child component - Implement detectProjectDir() utility that walks up directory tree looking for .fusion/fusion.db - Update package entry point with context exports and demo app - Add @fusion/core as dependency to TUI package - Add comprehensive tests for FusionProvider, useFusion hook, and detectProjectDir - Add API documentation to README with usage examples

* Walks up the directory tree starting from `startPath` (or `process.cwd()` by default)

|
* looking for `.fusion/fusion.db`. Returns the project root directory (parent of `.fusion/`)

|
|
* // Find project from current directory

|
* const projectPath = detectProjectDir();
|

*
|
|
* // Find project from a specific directory
