chore: remove all better-sqlite3 references from codebase (#357)

* fix: export/import scripts now use API instead of direct DB access

Export script fix:
- Add format=json parameter to SearchManager for raw data output
- Add getSdkSessionsBySessionIds method to SessionStore
- Add POST /api/sdk-sessions/batch endpoint to DataRoutes
- Refactor export-memories.ts to use HTTP API

Import script fix:
- Add import methods to SessionStore with duplicate detection
- Add POST /api/import endpoint to DataRoutes
- Refactor import-memories.ts to use HTTP API

* fix: update analyze-transformations-smart.js to use bun:sqlite

Replace better-sqlite3 import with bun:sqlite to align with v7.1.0 migration.

* chore: remove all better-sqlite3 references from codebase

- Updated scripts/analyze-transformations-smart.js to use bun:sqlite
- Merged PR #332: Refactored import/export scripts to use worker API instead of direct DB access
- Updated PM2-to-Bun migration documentation

All better-sqlite3 references have been removed from source code.
Documentation references remain as appropriate historical context.

* build: update plugin artifacts with merged changes

Include built artifacts from PR #332 merge and analyze-transformations-smart.js update.
