feat(heartbeat): save emails to KB + fix memory symlink access

- heartbeat saves unread whitelisted emails via email_process --save --json
- fix: add --add-dir so Claude CLI subprocess can access memory/ symlink
- email_check/process: use BODY.PEEK[] to avoid marking emails as read
- email_process: simplify credential loading via credential_store only
- config: heartbeat interval 30→120min, quiet hours end 08→07
