- Add YAML-configurable memory schemas (cards, events, entities, etc.)
- Implement MemoryReAct with tool use (read/find/ls)
- Add schema-driven memory operations (write_uris/edit_uris/delete_uris)
- Implement memory patch handler for incremental updates
- Add comprehensive test suite

## Summary

Implement memory templating system (GitHub Issue #578) - a complete
rewrite of the memory extractor subsystem to support YAML-configurable
memory types instead of hardcoded categories.

## Key Changes

### Architecture
- Replace hardcoded 8 memory types with YAML-configurable schema system
- Add MemoryTypeRegistry to load memory type definitions from YAML files
- Dynamic Pydantic model generation from schema for type safety
- Field-level merge operations: PATCH, SUM, IMMUTABLE

### Memory Extraction Flow
- Implement ReAct orchestrator for single-pass memory updates
- MemoryUpdater for applying operations to storage
- Memory tools (read, search, ls) for ReAct loop
- Stable JSON parser with 5-layer fault tolerance

### File Naming & Storage
- Semantic filenames from template ({topic}.md instead of random IDs)
- Two memory modes: simple mode and template mode
- MEMORY_FIELDS HTML comment for structured metadata

### Configuration
- 9 YAML templates in openviking/prompts/templates/memory/
- memory_config.py for memory system configuration
- Dual-threshold compact upload mechanism in design doc

### Deletions
- Remove old memory_content.py, memory_data.py, memory_operations.py
- Remove memory_types.py, memory_utils.py, memory_patch.py
- Remove corresponding old test files

### Updated Components
- VLM backends (litellm, openai, volcengine) for new interfaces
- Session and service core integration
- Test suite for new architecture

## Summary

Fix missing parameters in commit_async() when calling extract_long_term_memories().
The synchronous commit() method correctly passes these parameters, but the async
version was missing them, causing memory extraction to be skipped.

## Changes

- Pass user=self.user, session_id=self.session_id, ctx=self.ctx
  in commit_async() when calling extract_long_term_memories()

## Summary

Fix JSON serialization error by converting FindResult object to dict
using its to_dict() method before returning from MemorySearchTool.

## Changes

- In MemorySearchTool.execute(), return search_result.to_dict()
  instead of search_result directly

Also rename schema_models.py to schema_model_generator.py for clarity.
