feat: Implement recursive core-memory database discovery and project listing

- Added `findAllCoreMemoryDatabases` function to recursively locate core-memory databases in nested project structures.
- Updated `listAllProjects` to utilize the new recursive function for improved project listing.
- Enhanced `getMemoriesFromProject` and `findMemoryAcrossProjects` to support nested project structures.

feat: Introduce spec context injection in hooks configuration

- Added a new hook configuration for "Spec Context Injection" to load project specs based on prompt keywords.

chore: Add gray-matter dependency for YAML frontmatter parsing

- Included `gray-matter` package in `package.json` for parsing YAML frontmatter in markdown files.

feat: Create Spec Index Builder tool for managing project specs

- Implemented `spec-index-builder.ts` to scan markdown files, extract YAML frontmatter, and generate index cache files for different spec dimensions.

feat: Develop Spec Init tool for initializing spec directories and seed documents

- Created `spec-init.ts` to set up the directory structure and seed documents for the spec system.

feat: Build Spec Keyword Extractor for keyword extraction from prompts

- Added `spec-keyword-extractor.ts` to extract keywords from user prompts, supporting both English and Chinese text.

feat: Implement Spec Loader for loading and filtering specs based on keywords

- Developed `spec-loader.ts` to handle loading of specs, filtering by read mode and keyword matches, and formatting output for CLI or hooks.
