build: bump version to 6.1.0

SQLite wallet (default), RocksDB chaindb (default), Boost removal
from common link, I2P startup performance fix (180s→27ms).

Migration is automatic and non-destructive:
- Wallet: BDB → SQLite on first open (original preserved as .bdb.bak)
- ChainDB: LevelDB → RocksDB on next start (via -chaindb flag)
