Sources: Velocity `HandshakeIntent.java:16`, `StateRegistry.java:883`, `ProtocolVersion.java:89`; ViaVersion `InitialBaseProtocol.java:55,133`. Distinction: the *Handshake intent=3* is a serverbound signal from the transferring client; the *Transfer clientbound packet* (Play state, 0x73 in 1.20.5/1.21) is what the originating server sends to instruct the client to reconnect. Both ship in 1.20.5. Velocity registers the clientbound `TransferPacket` from `MINECRAFT_1_20_5` in both CONFIG (0x0B) and PLAY (0x73) state (`StateRegistry.java:239-240, 819-821`).

These are Velocity's values; vanilla wiki IDs may differ per-snapshot but the shift pattern is confirmed.
