Removes the PROTOCOL_VERSION lockstep handshake across the bridge
transports. HandshakeMessage is now an empty marker indicating the
server is ready; the client sends StartupMessage next. Field-presence
and roundtrip behavioral tests are retained — tautological
version-literal assertions were deleted in Sprint 36.
After this lands, genuine schema drift surfaces as MessagePack
missing-field errors downstream, which is the intended signal per
D-192. Client ticket #875 is blocked by this commit and will ride
the same wave; server schema changes in #878 (character_archetype
removal) also depend on PROTOCOL_VERSION already being gone.
types.rs changes are bundled with the broader #877/#878 dead-code
sweep in the following commit, since they share the same file.

Fix all Clippy warnings across the server codebase (2411 insertions, 1341
deletions). Raise type-complexity-threshold to 750 and too-many-arguments
to 12 in .clippy.toml for idiomatic Bevy ECS system signatures. The server
now passes `cargo clippy -- --deny warnings` cleanly.

#556: HANDSHAKING state in sim_bridge.gd — decodes first framed message
as HandshakeMessage, validates vs Protocol.PROTOCOL_VERSION, 5s timeout,
handshake_complete/handshake_failed signals.
#342: IPC benchmark now reads and validates HandshakeMessage before
starting the timing loop.
