Add comprehensive tests for vector/semantic search functionality

- Implement full coverage tests for Embedder model loading and embedding generation
- Add CRUD operations and caching tests for VectorStore
- Include cosine similarity computation tests
- Validate semantic search accuracy and relevance through various queries
- Establish performance benchmarks for embedding and search operations
- Ensure edge cases and error handling are covered
- Test thread safety and concurrent access scenarios
- Verify availability of semantic search dependencies

-### Tool Context Protocols
-For all  tool usage, command syntax, and integration guidelines:
-- **Tool Strategy**: @~/.claude/workflows/tool-strategy.md
-- **Intelligent Context Strategy**: @~/.claude/workflows/intelligent-tools-strategy.md
-- **Context Search Commands**: @~/.claude/workflows/context-search-strategy.md
-
-**Context Requirements**:
-- Identify 3+ existing similar patterns before implementation
-- Map dependencies and integration points
-- Understand testing framework and coding conventions
-
-
-## Philosophy
-
-### Core Beliefs
-
-- **Pursue good taste** - Eliminate edge cases to make code logic natural and elegant
-- **Embrace extreme simplicity** - Complexity is the root of all evil
-- **Be pragmatic** - Code must solve real-world problems, not hypothetical ones
-- **Data structures first** - Bad programmers worry about code; good programmers worry about data structures
-- **Never break backward compatibility** - Existing functionality is sacred and inviolable
-- **Incremental progress over big bangs** - Small changes that compile and pass tests
-- **Learning from existing code** - Study and plan before implementing
-- **Clear intent over clever code** - Be boring and obvious
-- **Follow existing code style** - Match import patterns, naming conventions, and formatting of existing codebase
-- **Minimize changes** - Only modify what's directly required; avoid refactoring, adding features, or "improving" code beyond the request
-- **No unsolicited documentation** - NEVER generate reports, documentation files, or summaries without explicit user request. If required, save to .workflow/.scratchpad/
-
-### Simplicity Means
-
-- Single responsibility per function/class
-- Avoid premature abstractions
-- No clever tricks - choose the boring solution
-- If you need to explain it, it's too complex
-
-## Project Integration
-
-### Learning the Codebase
-
-- Find 3 similar features/components
-- Identify common patterns and conventions
-- Use same libraries/utilities when possible
-- Follow existing test patterns
-
-### Tooling
-
-- Use project's existing build system
-- Use project's test framework  
-- Use project's formatter/linter settings
-- Don't introduce new tools without strong justification
-
-
-### Fix, Don't Hide
-
-- **Solve problems, don't silence symptoms** - Skipped tests, `@ts-ignore`, empty catch, `as any`, excessive timeouts = hiding bugs, not fixing them
-
-**NEVER**:
-- Make assumptions - verify with existing code
-- Generate reports, summaries, or documentation files without explicit user request
-- Use suppression mechanisms (`skip`, `ignore`, `disable`) without fixing root cause
-
-**ALWAYS**:
-- Plan complex tasks thoroughly before implementation
-- Generate task decomposition for multi-module work (>3 modules or >5 subtasks)
-- Track progress using TODO checklists for complex tasks
-- Validate planning documents before starting development
-- Commit working code incrementally
-- Update plan documentation and progress tracking as you go
-- Learn from existing implementations
-- Stop after 3 failed attempts and reassess
-- **Edit fallback**: When Edit tool fails 2+ times on same file, try Bash sed/awk first, then Write to recreate if still failing
-
-## Platform-Specific Guidelines
-
-### Windows Path Format Guidelines
-- **MCP Tools**: Double backslash `D:\\path\\file.txt`
-- **Bash Commands**: Forward slash `D:/path/file.txt` or `/d/path/file.txt`
-- **Relative Paths**: Universal (works in both)
-
-#### **Content Uniqueness Rules**
-
-- **Each layer owns its abstraction level** - no content sharing between layers
-- **Reference, don't duplicate** - point to other layers, never copy content
-- **Maintain perspective** - each layer sees the system at its appropriate scale
-- **Avoid implementation creep** - higher layers stay architectural
