fix: SESSIONS_DIR env var and config dimension docs

- SESSIONS_DIR now reads from OPENCLAW_SESSIONS_DIR env var with fallback
- Fixes hardcoded path issue reported by community
- config.json: add embedding_dimensions (1024) and notes field
- Update version to 1.1 in config.json

Validated 4x:
1. SESSIONS_DIR line correct
2. config.json syntax valid
3. Both files syntax OK
4. Env var logic tested

Thanks to Rob Whyte @ Fort Myers Brewing for the suggestion.
