Adds a per-destination "Max Rate (Hz)" field that caps how often a route emits OSC messages. Coalesce semantics: when input arrives faster than the configured rate, only the most recent message survives the period and is emitted at the next interval boundary; nothing is sent during silence. Useful for streaming sources (PSN, ArtNet/sACN-driven OSC bridges) where the input rate can saturate downstream consoles. Scope: OSC outputs only. sACN, ArtNet, MIDI, OTP, and PSN destinations are unaffected. Default 0 = unlimited; existing configs are unchanged. Refactor: per-destination dispatch in ProcessRecvPacket extracted into DispatchBuiltPacket, which returns whether a real send happened so the rate-limit timer only advances on actual sends. The flush pass runs once per main loop iteration after the TCP-clients section.
Adds a per-destination "Only Changes" checkbox that drops outgoing OSC messages whose bytes exactly match the previous send to that destination. Useful for streaming sources where the talent is often stationary and there's no point repeating the same value. When combined with the rate limit, the rate-limit timer only advances on a real send, so a stationary period followed by a sudden change emits immediately rather than waiting another full period. Comparison is byte-for-byte on the built OSC packet. Scope: OSC outputs only.

Adds a per-destination "Only Changes" checkbox to each route. When enabled, outgoing OSC messages whose bytes are byte-identical to the previous send to that destination are suppressed.
Behavior
Stacks on #53
This PR depends on the refactor and the
DispatchBuiltPackethelper from the rate-limit PR. The diff shown here is cumulative until #53 lands; after that, this PR will rebase and show only its own changes.Implementation
DispatchBuiltPacket. On a successful send, the built packet is stashed inlastSentPacketfor the next compare..osc.txt(onlyChanges). Old configs load unchanged; new configs round-trip.
