fix: add missing cline and copilot to default agents seed

The smriti_session_meta table has a FOREIGN KEY on agent_id referencing
smriti_agents, but only claude-code, codex, and cursor were seeded.
This caused FK constraint failures when ingesting copilot or cline
sessions on a clean database.

Closes #30
