* feat: MCP server optimization with tool consolidation and vertical slice architecture

- Consolidated MCP tools from ~20 to 8 tools for improved UX
- Restructured to vertical slice architecture (features/domain pattern)
- Optimized payload sizes with truncation and array count replacements
- Changed default include_closed to true for better task visibility
- Moved RAG module to features directory structure
- Removed legacy modules directory in favor of feature-based organization

Key improvements:
- list_tasks, manage_task (create/update/delete consolidated)
- list_projects, manage_project (create/update/delete consolidated)
- list_documents, manage_document (create/update/delete consolidated)
- list_versions, manage_version (create/restore consolidated)
- Reduced default page size from 50 to 10 items
- Added search query support to list operations

* feat: Consolidate MCP tools and rename list_* to find_*

Major refactoring of MCP tools to reduce complexity and improve naming:

## Tool Consolidation (22 → ~10 tools)
- Consolidated CRUD operations into two tools per domain:
  - find_[resource]: Handles list, search, and get single item
  - manage_[resource]: Handles create, update, delete with "action" parameter
- Removed backward compatibility/legacy function mappings
- Optimized response payloads with truncation (1000 char limit for projects/tasks)

## Renamed Functions
- list_projects → find_projects
- list_tasks → find_tasks
- list_documents → find_documents
- list_versions → find_versions

## Bug Fixes
- Fixed supabase query chaining bug where .or_() calls overwrote previous conditions
- Fixed search implementation to handle single vs multiple terms correctly

## Test Updates
- Updated all tests to use new consolidated tools
- Removed problematic test_consolidated_tools.py
- Fixed error type assertions to match actual responses
- All 44 tests passing

## Documentation Updates
- Updated CLAUDE.md with new tool names and patterns
- Updated MCP instructions with consolidated tool examples
- Added guidance to avoid backward compatibility code

## API Changes
- Updated API route defaults: include_closed=True, per_page=10
- Aligned defaults with consolidated tool implementations
