fix: sync .env.example with actual config in src/config.rs

Removed outdated options that don't exist in code:
- NGIT_SYNC_STARTUP_DELAY_SECS
- NGIT_SYNC_RECONNECT_DELAY_SECS
- NGIT_SYNC_RECONNECT_LOOKBACK_DAYS
- NGIT_SYNC_STARTUP_JITTER_MS
- NGIT_ARCHIVE_MODE (future/planned)

Added missing options that exist in code:
- NGIT_SYNC_DISCONNECT_CHECK_INTERVAL_SECS
- NGIT_SYNC_BASE_BACKOFF_SECS
- NGIT_SYNC_DISABLE_NEGENTROPY
- NGIT_REJECTED_HOT_CACHE_DURATION_SECS
- NGIT_REJECTED_COLD_INDEX_EXPIRY_SECS
- NGIT_NAUGHTY_LIST_EXPIRATION_HOURS

All environment variables now match exactly between src/config.rs
and .env.example, with consistent defaults and descriptions.
