Add multi-account Gmail polling with per-account seen tracking, updated
onboarding flow, and config/env resolution.
Based on jasoncarreira's work in #214, rebased onto current main and
cleaned up:
- parseGmailAccounts() extracted to polling/service.ts with 10 unit tests
- Per-account seen email tracking (Map<string, Set<string>>) with legacy
migration from single-account format
- Onboarding supports multi-select for existing accounts + add new
- Config resolution: polling.gmail.accounts > integrations.google.accounts
(legacy) > GMAIL_ACCOUNT env (comma-separated)
- GoogleAccountConfig type for per-account service selection
- Updated docs/configuration.md
Closes#214.

Interface-first multi-agent orchestration layer.
- Define AgentSession interface capturing the contract consumers depend on
- LettaBot implements AgentSession (already has all methods, now explicit)
- LettaGateway manages multiple named AgentSession instances
- Update heartbeat, cron, polling, API server to depend on interface, not concrete class
- 8 new gateway tests
No behavioral changes. Consumers that used LettaBot now use AgentSession interface,
enabling multi-agent without modifying consumer code.
