Remove conversation context/recall system from ClaudeTools

Completely removed the database context recall system while preserving
database tables for safety. This major cleanup removes 80+ files and
16,831 lines of code.

What was removed:
- API layer: 4 routers (conversation-contexts, context-snippets,
  project-states, decision-logs) with 35+ endpoints
- Database models: 5 models (ConversationContext, ContextSnippet,
  DecisionLog, ProjectState, ContextTag)
- Services: 4 service layers with business logic
- Schemas: 4 Pydantic schema files
- Claude Code hooks: 13 hook files (user-prompt-submit, task-complete,
  sync-contexts, periodic saves)
- Scripts: 15+ scripts (import, migration, testing, tombstone checking)
- Tests: 5 test files (context recall, compression, diagnostics)
- Documentation: 30+ markdown files (guides, architecture, quick starts)
- Utilities: context compression, conversation parsing

Files modified:
- api/main.py: Removed router registrations
- api/models/__init__.py: Removed model imports
- api/schemas/__init__.py: Removed schema imports
- api/services/__init__.py: Removed service imports
- .claude/claude.md: Completely rewritten without context references

Database tables preserved:
- conversation_contexts, context_snippets, context_tags,
  project_states, decision_logs (5 orphaned tables remain for safety)
- Migration created but NOT applied: 20260118_172743_remove_context_system.py
- Tables can be dropped later when confirmed not needed

New files added:
- CONTEXT_SYSTEM_REMOVAL_SUMMARY.md: Detailed removal report
- CONTEXT_SYSTEM_REMOVAL_COMPLETE.md: Final status
- CONTEXT_EXPORT_RESULTS.md: Export attempt results
- scripts/export-tombstoned-contexts.py: Export tool for future use
- migrations/versions/20260118_172743_remove_context_system.py

Impact:
- Reduced from 130 to 95 API endpoints
- Reduced from 43 to 38 active database tables
- Removed 16,831 lines of code
- System fully operational without context recall

Reason for removal:
- System was not actively used (no tombstoned contexts found)
- Reduces codebase complexity
- Focuses on core MSP work tracking functionality
- Database preserved for safety (can rollback if needed)
