general improvements (#17)

* refactor(hooks): simplify hook execution with shared context

- [x] Extract BaseInput struct to eliminate duplicate fields across hooks
- [x] Create RunHook handler pattern for session-start and user-prompt
- [x] Create RunStatuslineHook for fast statusline rendering without worker startup
- [x] Add HookContext struct to pass port, project, CWD, SessionID to handlers
- [x] Add db/interface.go with ObservationReader/Writer interfaces
- [x] Add comprehensive conflict management tests in sqlite/conflict_test.go
- [x] Add vector client tests for Count, ModelVersion, NeedsRebuild, GetStaleVectors
- [x] Add FilterByThreshold helper tests for query result filtering
- [x] Make handlers_test more robust for network-dependent update checks
- [x] Update package versions in UI

* Move to GORM + general cleanup

* feat(mcp): add observation relations discovery and scoring integration

- [x] Add find_related_observations MCP tool for discovering related observations by confidence
- [x] Integrate scoring calculator and recalculator into MCP server initialization
- [x] Add pattern, relation, and session stores to MCP server dependencies
- [x] Register MCP server in Claude Code settings during plugin installation
- [x] Update install scripts (bash, PowerShell) to configure MCP server settings
- [x] Switch plugin manifest files to template-based versioning (plugin.json.tpl, marketplace.json.tpl)
- [x] Update all MCP server tests to pass new dependency parameters
